New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Tom Greer (tng*) of the United States. Tom is a member of the Sicituradastra. team.

The AP25 was returned on 12 Sep 2016 21:52:58 UTC. It was found by an Nvidia GTX 1080 on an Intel(R) Xeon(R) CPU E5-2623 v3 @ 3.00GHz running Microsoft Windows 10 Professional x64 Edition. It took about 21 minutes and 36 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Bryan Little (mfl0p) of the United States and was returned on 13 September 2016 10:51:23 UTC. This task was run on an Intel(R) Core(TM) i3-6100 CPU @ 3.70GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 13 hours, 3 minutes and 5 seconds to complete.

The progression is written as 223696034591087459+1731112*23#*n for n=0..24. Credits are as follows:

Finder: Tom Greer
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Magnus Karlsson (Mankka*) of Finland. Magnus is a member of the Sicituradastra. team.

The AP25 was returned on 15 Sep 2016 16:00:31 UTC. It was found by an AMD Cypress GPU on an Intel(R) Core(TM) i7 CPU 930 @ 2.80GHz running Microsoft Windows 7 Professional x64 Edition. It took about 8 hours, 22 minutes and 27 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Hiroyuki Okazaki (zunewantan) of Japan and was returned on 16 September 2016 1:14:28 UTC. This task was run on an Intel(R) Core(TM) i5-4590S CPU @ 3.00GHz running Microsoft Windows 7 Professional x64 Edition. The double check took about 17 hours, 11 minutes and 22 seconds to complete. Hiroyuki is a member of the Aggie The Pew team.

The progression is written as 235660731794099011+1949500*23#*n for n=0..24. Credits are as follows:

Finder: Magnus Karlsso
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Honza Cholt (Honza) of the Czech Republic. Honza is a member of the BOINC.SK team.

The AP25 was returned on 16 Sep 2016 21:24:44 UTC. It was found by an Nvidia GTX 1070 GPU on an Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz running Microsoft Windows 10 Professional x64 Edition. It took about 25 minutes and 27 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by user (alfRKnet) of Germany and was returned on 18 September 2016 6:58:13 UTC. This task was run on an Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 15 hours, 30 minutes and 13 seconds to complete. User alfRKnet is a member of the Rechenkraft.net team.

The progression is written as 124464776168666173+2104383*23#*n for n=0..24. Credits are as follows:

Finder: Honza Cholt
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Takeshi Nakamura (kurogane-t) of Japan. Takeshi is a member of the BOINC@MIXI team.

This is only the fifth AP26 known to exist, and the second found at PrimeGrid.

The AP26 was returned on 3 November 2016 23:25:42 UTC. It was found by an Nvidia GTX 1070 GPU on an Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz running Microsoft Windows 10
Core x64 Edition. It took about 30 minutes and 1 second to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by James Nobis (quel) of the United States and was returned on 4 November 2016 3:37:51 UTC. This task was run on an ATI Tahiti GPU on an AMD Opteron(tm) Processor 6348 running Linux. The double check took about 1 hour, 20 minutes, and 40 seconds to complete. James is a member of the Sicituradastra. team.

The progression is written as 149836681069944461+7725290*23#*n for n=0..25. Credits are as follows:

Finder: Takeshi Nakamura
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Hiroyuki Okazaki (zunewantan) of Japan. Hiroyuki is a member of the Aggie The Pew team.

The AP25 was returned on 17 November 2016 1:06:31 UTC. It was found by an Intel(R) Core(TM) i5-4590S CPU @ 3.00GHz running Microsoft Windows 7 Professional x64 Edition. It took about 15 hours, 45 minutes and 12 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Casey Townsend (Casey) of the United States and was returned on 17 November 2016 9:33:44 UTC. This task was run on an AMD CAL Hawaii GPU on an AMD Phenom(tm) II X4 965 running Microsoft Windows 7 Home Premium x64 Edition. The double check took about 43 minutes and 31 seconds to complete. Casey is a member of the FRESCA team.

The progression is written as 299460668118437929+9026994*23#*n for n=0..24. Credits are as follows:

Finder: Hiroyuki Okazaki
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Rafael Trigueiro (Rafael) of Brazil. Rafael is a member of the LinusTechTips_Team.

The AP25 was returned on 18 November 2016 17:23:35 UTC. It was found by an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i5-6600K CPU @ 3.50GHz running Microsoft Windows 10 Professional x64 Edition. It took about 35 minutes and 48 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Koichi Soraku (JG4KEZ(Koichi Soraku)) of Japan and was returned on 18 November 2016 19:16:30 UTC. This task was run on an NVIDIA GeForce GTX TITAN GPU on an Intel(R) Core(TM) i7-5775C CPU @ 3.30GHz running Microsoft Windows 7 Home Premium x64 Edition. The double check took about 1 hour, 16 minutes and 14 seconds to complete. Koichi is a member of the BOINC@MIXI team.

The progression is written as 322477370185894411+9633039*23#*n for n=0..24. Credits are as follows:

Finder: Rafael Trigueiro
Project: PrimeGrid

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Josef Matousek (vinn [Czech National Team]) of the Czech Republic. Josef is a member of the Czech National Team.

The AP25 was returned on 19 November 2016 2:02:34 UTC. It was found by an NVIDIA GeForce GTX 980 Ti GPU on an Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz running Microsoft Windows 10 Professional x64 Edition. It took about 24 minutes and 48 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Timo Schneider (XSmeagolX) of Germany and was returned on 19 November 2016 2:19:52 UTC. This task was run on an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 41 minutes and 46 seconds to complete. Timo is a member of the SETI.Germany team.

The progression is written as 327723838632911059+10176298*23#*n for n=0..24. Credits are as follows:

Finder: Josef Matousek
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Ross Goudie (Ross*) of New Zealand. Ross is a member of the Sicituradastra. team.

The AP25 was returned on 18 November 2016 20:24:49 UTC. It was found by an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Core(TM) i7-6850K CPU @ 3.60GHz running Microsoft Windows 10 Core x64 Edition. It took about 21 minutes and 37 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Hans Rensen ([DPC] hansR) of the Netherlands and was returned on 19 November 2016 10:16:35 UTC. This task was run on an NVIDIA Quadro K3000M GPU on an Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 7 hours, 10 minutes and 58 seconds to complete. Hans is a member of the Dutch Power Cows team.

The progression is written as 84314670428700353+9954590*23#*n for n=0..24. Credits are as follows:

Finder: Ross Goudie
Project: PrimeGrid

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is John S Chambers (Johnny Rotten) of the United States. John is a member of the SETI.USA team.

The AP25 was returned on 19 November 2016 2:27:31 UTC. It was found by an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz running Microsoft Windows Professional x64 Edition. It took about 18 minutes and 47 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Josef Matousek (vinn [Czech National Team]) of the Czech Republic and was returned on 19 November 2016 8:21:04 UTC. This task was run on an NVIDIA Tesla K20m GPU on an Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz running Microsoft Windows Server 2012 R2 Standard x64 Edition. The double check took about 1 hour, 55 minutes and 35 seconds to complete. Josef is a member of the Czech National Team.

The progression is written as 193513604089287343+10189009*23#*n for n=0..24. Credits are as follows:

Finder: John S Chambers
Project: PrimeGrid

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Stephen Draycott (Stephen Draycott) of the United Kingdom.

The AP25 was returned on 20 November 2016 2:47:04 UTC. It was found by an NVIDIA Quadro K5200 GPU on an Intel(R) Xeon(R) CPU E5-2670 v3 @ 2.30GHz running Microsoft Windows 10 Professional x64 Edition. It took about 1 hour, 34 minutes and 19 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Brian Herbers (Shadowlurker) of the United States and was returned on 20 November 2016 18:04:32 UTC. This task was run on an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i5-4670 CPU @ 3.40GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 1 hour, 15 minutes and 25 seconds to complete. Brian is a member of the SETI.USA team.

The progression is written as 203563934890169353+11105961*23#*n for n=0..24. Credits are as follows:

Finder: Stephen Draycott
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Stefan Larsson (288larsson) of Sweden. Stefan is a member of the Sicituradastra. team.

The AP25 was returned on 21 November 2016 10:01:32 UTC. It was found by an AMD CAL Fiji GPU on an Intel(R) Core(TM) i5-4670K CPU @ 3.40GHz running Linux. It took about 59 minutes and 58 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Zdenek Vasku (HA-SOFT, s.r.o.) of the Czech Republic and was returned on 23 November 2016 3:04:07 UTC. This task was run on an NVIDIA GeForce GTX 590 GPU on an Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz running Linux. The double check took about 1 hour, 40 minutes and 42 seconds to complete. Zdenek is a member of the Czech National Team.

The progression is written as 231349139005158193+12169920*23#*n for n=0..24. Credits are as follows:

Finder: Stefan Larsson
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Mike Kinney (Mektacular) of the United States. Mike is a member of the Crunching@EVGA team.

The AP25 was returned on 21 November 2016 16:21:09 UTC. It was found by an NVIDIA GeForce GTX 1070 GPU on an Intel(R) Core(TM) i7-6850K CPU @ 3.60GHz running Microsoft Windows 10 Professional x64 Edition. It took about 23 minutes and 26 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by 王者也 (之乎) of China and was returned on 23 November 2016 20:14:42 UTC. This task was run on an NVIDIA GeForce GTX 1070 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 25 minutes and 23 seconds to complete. 王者也 is a member of Team China.

The progression is written as 290884103695102903+12444168*23#*n for n=0..24. Credits are as follows:

Finder: Mike Kinney
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is James Krauss (Grebuloner) of the United States. James is a member of The Knights Who Say Ni! team.

The AP25 was returned on 19 November 2016 18:12:03 UTC. It was found by an NVIDIA GeForce GTX 980 Ti GPU on an Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz running Microsoft Windows 7 Professional x64 Edition. It took about 24 minutes and 57 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Steven Schapendonk (HK-Steve) of Switzerland and was returned on 24 November 2016 2:02:29 UTC. This task was run on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 11 hours, 35 minutes and 4 seconds to complete. Steven is a member of the Crunching@EVGA team.

The progression is written as 183800317923336901+10816541*23#*n for n=0..24. Credits are as follows:

Finder: James Krauss
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is David Walling (Dave) of the United Kingdom. David is a member of Aggie The Pew team.

The AP25 was returned on 30 November 2016 6:18:54 UTC. It was found by an NVIDIA GeForce GTX 580 GPU on an Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz running Microsoft Windows 7 Home Premium x64 Edition. It took about 1 hour, 19 minutes and 21 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Andrew Dicker (Andrew Dicker) of Australia and was returned on 30 November 2016 18:43:28 UTC. This task was run on an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i7-4770S CPU @ 3.10GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 47 minutes and 10 seconds to complete. Andrew is a member of the Webberites team.

The progression is written as 228744309021939859+14918987*23#*n for n=0..24. Credits are as follows:

Finder: David Walling
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Stefan Hofacker (shofacker) of Germany. Stefan is a member of SETI.Germany team.

The AP25 was returned on 30 November 2016 14:08:29 UTC. It was found by an NVIDIA GeForce GTX 780 Ti GPU on an Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz running Microsoft Windows 10 Enterprise N x64 Edition. It took about 1 hour and 41 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Ingrid Anita Gillesøy (AriZonaMoon*) of Norway and was returned on 1 December 2016 15:34:13 UTC. This task was run on an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 41 minutes and 1 second to complete. Ingrid is a member of the Sicituradastra. team.

The progression is written as 240091225937752601+14964187*23#*n for n=0..24. Credits are as follows:

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is user skgiven. User skgiven is a member of FTW team.

The AP25 was returned on 1 December 2016 20:39:05 UTC. It was found by an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz running Microsoft Windows 10 Professional x64 Edition. It took about 42 minutes and 10 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Jan-Peter Fischer (JayPi) of Germany and was returned on 1 December 2016 20:44:00 UTC. This task was run on an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i7-4770K CPU @ 3.50GHz running Microsoft Windows 7 Ultimate x64 Edition. The double check took about 1 hour, 33 minutes and 8 seconds to complete. Jan-Peter is a member of the SETI.Germany team.

The progression is written as 117409484129625731+15143792*23#*n for n=0..24. Credits are as follows:

Finder: user "skgiven"
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Evelyn Chew (Crackenback) of Australia. Evelyn is a member of BOINC@AUSTRALIA team.

The AP25 was returned on 1 December 2016 1:25:23 UTC. It was found by an NVIDIA GeForce GTX 1070 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 7 Enterprise x64 Edition. It took about 27 minutes and 5 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Konrad Chudzik (xXUnRealXx) of Poland and was returned on 2 December 2016 13:03:46 UTC. This task was run on an NVIDIA GeForce GTX 980 Ti GPU on an Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 24 minutes and 59 seconds to complete. Konrad is a member of the Gridcoin team.

The progression is written as 298190132293964681+15023287*23#*n for n=0..24. Credits are as follows:

Finder: Evelyn Chew
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Eirik Lunner (Orange_1050) of Norway. Eirik is a member of Crunching@EVGA team.

The AP25 was returned on 3 December 2016 18:59:45 UTC. It was found by an NVIDIA GeForce GTX 1060 6GB GPU on an Intel(R) Xeon(R) CPU E3-1245 v5 @ 3.50GHz running Microsoft Windows 7 Professional x64 Edition. It took about 36 minutes and 58 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Koichi Soraku (JG4KEZ(Koichi Soraku)) of Japan and was returned on 3 December 2016 20:08:45 UTC. This task was run on an NVIDIA GeForce GTX 1070 GPU on an Intel(R) Core(TM) i7-5775C CPU @ 3.30GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 27 minutes and 51 seconds to complete. Koichi is a member of the BOINC@MIXI team.

The progression is written as 148375001202532501+15439522*23#*n for n=0..24. Credits are as follows:

Finder: Eirik Lunner
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Koichi Soraku (JG4KEZ(Koichi Soraku)) of Japan. Koichi is a member of the BOINC@MIXI team.

This is only the sixth AP26 known to exist, and the third found at PrimeGrid.

The AP26 was returned on 11 December 2016 20:06:09 UTC. It was found by an Nvidia GTX 1070 GPU on an Intel(R) Core(TM) i7-5775C CPU @ 3.30GHz running Microsoft Windows 10
Professional x64 Edition. It took about 27 minutes and 19 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Dirk Kraemer (DoctorNow) of Germany and was returned on 12 December 2016 10:44:25 UTC. This task was run on an Nvidia GTX 760 GPU on an AMD Phenom(tm) II X6 1045T Processor running Microsoft Windows Vista Home Premium x64 Edition. The double check took about 2 hours, 22 minutes, and 8 seconds to complete. Dirk is a member of the BOINC Confederation team.

The progression is written as 142099325379199423+16549135*23#*n for n=0..25. Credits are as follows:

Finder: Koichi Soraku
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Roland Klepel (klepel) of Peru. Roland is a member of the Gridcoin team.

The AP25 was returned on 20 December 2016 9:12:31 UTC. It was found by an NVIDIA GeForce GTX 970 GPU on an AMD FX(tm)-6100 Six-Core Processor running linux. It took about 1 hour, 28 minutes and 55 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Brent Schneider (KWSN-SpongeBob SquarePants) of Nepal and was returned on 21 December 2016 23:06:36 UTC. This task was run on an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Enterprise x64 Edition. The double check took about 25 minutes and 26 seconds to complete. Brent is a member of The Knights Who Say Ni! team.

The progression is written as 295363409604322229+17257904*23#*n for n=0..24. Credits are as follows:

Finder: Roland Klepel
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

The AP25 was returned on 12 January 2017 23:15:04 UTC. It was found by an NVIDIA GeForce GTX 1060 6GB GPU on an Intel(R) Core(TM) i3-6100 CPU @ 3.70GHz running Microsoft Windows 10 Core x64 Edition. It took about 36 minutes and 45 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Mike Kinney (Mektacular) of the United States and was returned on 12 January 2017 23:19:01 UTC. This task was run on an NVIDIA GeForce GTX 980 Ti GPU on an Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 23 minutes and 55 seconds to complete. Mike is a member of the Crunching@EVGA team.

The progression is written as 171104686521473149+19323763*23#*n for n=0..24. Credits are as follows:

Finder: Bryan Little
Project: PrimeGrid

The AP25 was returned on 22 February 2017 14:22:23 UTC. It was found by an NVIDIA GeForce GTX 750 Ti GPU on an Intel(R) Xeon(R) CPU E5-2670 0 @ 2.60GHz running Linux. It took about 2 hours, 36 minutes and 57 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Grzegorz Roman Granowski (Grzegorz Roman Granowski) of Poland and was returned on 23 February 2017 2:57:18 UTC. This task was run on an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Xeon(R) CPU E5-2660 v4 @ 2.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 21 minutes and 20 seconds to complete. Grzegorz is a member of the BOINC@Poland team.

The progression is written as 234934262624764103+22561202*23#*n for n=0..24. Credits are as follows:

Finder: Syracuse University

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Anthony Ayiomamitis (Anthony Ayiomamitis) of Greece. Anthony is a member of the Aggie The Pew team.

The AP25 was returned on 5 March 2017 0:56:16 UTC. It was found by an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Professional x64 Edition. It took about 19 minutes and 9 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by John Parker (Mike Parker) of the United States and was returned on 5 March 2017 2:03:23 UTC. This task was run on an NVIDIA GeForce GTX 960 GPU on an Intel(R) Core(TM) i7-5820K CPU @ 3.30GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 1 hour, 3 minutes and 34 seconds to complete. John is a member of the SETI.USA team.

The progression is written as 233662486570847311+23473713*23#*n for n=0..24. Credits are as follows:

Finder: Anthony Ayiomamitis
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Vince Splain (yank) of the United States. Vince is a member of the US Navy team.

The AP25 was returned on 6 March 2017 22:39:49 UTC. It was found by an NVIDIA GeForce GTX 980 GPU on an Intel(R) Core(TM) i7-5960X CPU @ 3.00GHz running Microsoft Windows 7 Professional x64 Edition. It took about 47 minutes and 35 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Roger Karpin (Roger) of Australia and was returned on 6 March 2017 23:33:49 UTC. This task was run on a CAL AMD Radeon HD 7870/7950/7970/R9 280/R9 280X series (Tahiti) GPU on an AMD Phenom(tm) II X6 1100T Processor running Microsoft Windows 7 Home Premium x64 Edition. The double check took about 1 hour, 17 minutes and 43 seconds to complete. Roger is a member of the Aggie The Pew team.

The progression is written as 73237102080888511+23647405*23#*n for n=0..24. Credits are as follows:

Finder: Vince Splain
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is user Autumn_Beijing of China.

The AP25 was returned on 25 March 2017 8:51:34 UTC. It was found by an AMD Radeon HD 8750A GPU on an Intel(R) Core(TM) i5-4570S CPU @ 2.90GHz running Microsoft Windows 7 Ultimate x64 Edition. It took about 11 hours, 56 minutes and 32 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Svilen Metodiev Dimitrov (svilen_metodiev_dimitrov) of Bulgaria and was returned on 25 March 2017 19:20:46 UTC. This task was run on an NVIDIA GeForce 940MX GPU on an Intel(R) Core(TM) i3-7100U CPU @ 2.40GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 3 hours, 35 minutes and 18 seconds to complete. Svilen is a member of the Gridcoin team.

The progression is written as 264703230462051737+25208577*23#*n for n=0..24. Credits are as follows:

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Erik Klein (E Klein) of the United States. Erik is a member of the USA team.

The AP25 was returned on 10 April 2017 00:50:35 UTC. It was found by an NVIDIA GeForce GTX 960 GPU on an Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz running Microsoft Windows 10 Core x64 Edition. It took about 1 hour, 0 minutes and 37 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by an anonymous PrimeGrid user and was returned on 10 April 2017 14:37:10 UTC. This task was run on an NVIDIA GeForce GTX 970 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 41 minutes and 37 seconds to complete.

The progression is written as 211810229255864971+26698740*23#*n for n=0..24. Credits are as follows:

Finder: Erik Klein
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

The AP25 was returned on 8 May 2017 16:01:20 UTC. It was found by an NVIDIA GeForce GTX TITAN X GPU on an Intel(R) Core(TM) i7-5960X CPU @ 3.00GHz running Microsoft Windows 10 Professional x64 Edition. It took about 24 minutes and 56 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by user jay zhao of Canada and was returned on 9 May 2017 06:06:48 UTC. This task was run on an Nvidia Quadro K620 GPU on an Intel(R) Xeon(R) CPU E5-1620 v3 @ 3.50GHz running Linux. The double check took about 3 hours, 48 minutes and 39 seconds to complete.

The progression is written as 228315362514429847+29165712*23#*n for n=0..24. Credits are as follows:

Finder: Tuna Ertemalp
Project: PrimeGrid

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is William Donovan (Williamd007) of the United States. William is a member of the The Knights Who Say Ni! team.

The AP25 was returned on 17 June 2017 8:31:38 UTC. It was found by an NVIDIA GeForce GTX 1070 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Core x64 Edition. It took about 21 minutes and 49 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Grzegorz Roman Granowski (Grzegorz Roman Granowski) of Poland and was returned on 17 June 2017 13:03:55 UTC. This task was run on a NVIDIA GeForce GTX 1080 GPU on an Intel(R) Xeon(R) CPU E5-2660 v4 @ 2.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 19 minutes and 51 seconds to complete. Grzegorz is a member of the BOINC@Poland team.

The progression is written as 296950539631234873+32252465*23#*n for n=0..24. Credits are as follows:

Finder: William Donovan
Project: PrimeGrid

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Wolfgang Schwieger (DeleteNull) of Germany. Wolfgang is a member of the SETI.Germany team.

The AP25 was returned on 29 July 2017 19:45:16 UTC. It was found by an NVIDIA GeForce GTX 980 GPU on an AMD Ryzen 5 1600X Six-Core Processor running Microsoft Windows 10 Professional x64 Edition. It took about 36 minutes and 35 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Paweł Feruś (mindc) of Poland and was returned on 6 August 2017 20:05:37 UTC. This task was run on an Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz running Linux. The double check took about 1 day, 10 hours, 24 minutes and 41 seconds to complete. Paweł is a member of the BOINC@Poland team.

The progression is written as 172620809233105201+35156983*23#*n for n=0..24. Credits are as follows:

Finder: Wolfgang Schwieger
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is David E. Miller (dem0707) of The United States. David is a member of the Crunching@EVGA team.

The AP25 was returned on 19 August 2017 14:04:32 UTC. It was found by an NVIDIA GeForce GTX 980 GPU on an Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz running Microsoft Windows 7 Professional x64 Edition. It took about 40 minutes and 50 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Jan Harlass (Jan Harlass) of Germany and was returned on 20 August 2017 15:21:41 UTC. This task was run on an NVIDIA Quadro K620 on an Intel(R) Xeon(R) CPU E5-1620 v3 @ 3.50GHz running Linux. The double check took about 3 hours, 49 minutes and 16 seconds to complete. Jan is a member of the Planet 3DNow! team.

The progression is written as 320382581839925153+36759418*23#*n for n=0..24. Credits are as follows:

Finder: David E. Miller
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

The AP25 was returned on 28 August 2017 01:02:09 UTC. It was found by an NVIDIA GeForce GTX 750 Ti GPU on an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz running Microsoft Windows 10 Core x64 Edition. It took about 1 hour, 58 minutes and 37 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Grzegorz Roman Granowski (Grzegorz Roman Granowski) of Poland and was returned on 29 August 2017 05:04:53 UTC. This task was run on an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Xeon(R) CPU E5-2660 v4 @ 2.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 21 minutes and 53 seconds to complete. Grzegorz is a member of the BOINC@Poland team.

The progression is written as 96256695044976793+37286573*23#*n for n=0..24. Credits are as follows:

Finder: Bryan Little
Project: PrimeGrid

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Bruce E. Slade (Renix1943) of the United States. Bruce is a member of the Aggie The Pew team.

This is only the seventh AP26 known to exist, and the fourth found at PrimeGrid.

The AP26 was returned on 5 September 2017 08:23:41 UTC. It was found by an Nvidia GTX 970 GPU on an Intel(R) Core(TM) i3-6100 CPU @ 3.70GHz running Microsoft Windows 10
Core x64 Edition. It took about 40 minutes and 57 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Axel Schneider (axels) of Germany and was returned on 5 September 2017 19:34:24 UTC. This task was run on an Nvidia GTX 680 GPU on an Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz running Microsoft Windows 7 Home Premium x64 Edition. The double check took about 2 hours, 6 minutes, and 6 seconds to complete. Axel is a member of the SETI.Germany team.

The progression is written as 48277590120607451+37835074*23#*n for n=0..25. Credits are as follows:

Finder: Bruce E. Slade
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Wolfgang Schwieger (DeleteNull) of Germany. Wolfgang is a member of the SETI.Germany team.

The AP25 was returned on 1 October 2017 12:01:46 UTC. It was found by an NVIDIA GeForce GTX 1080 GPU on an AMD Opteron(tm) Processor 6344 running Linux openSUSE. It took about 23 minutes and 24 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 was double checked by Jan Gruyaert (jgruyaert) of Belgium and was returned on 1 October 2017 15:16:50 UTC. This task was run on an NVIDIA GeForce GTX 1060 GPU on an Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 40 minutes and 19 seconds to complete. Jan is a member of the Gridcoin team.

The progression is written as 282340243066022987+39699195*23#*n for n=0..24. Credits are as follows:

Finder: Wolfgang Schwieger
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

The AP25 was returned on 2 October 2017 9:35:40 UTC. It was found by an NVIDIA GeForce GTX 980 Ti GPU on an AMD FX-8370E Eight-Core Processor running Microsoft Windows 7 Ultimate x64 Edition. It took about 27 minutes and 44 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 was double checked by Lubomir Belko (Lubomir Belko) of Slovakia and was returned on 2 October 2017 20:46:40 UTC. This task was run on an NVIDIA GeForce GTX 960M GPU on an Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 2 hours, 5 minutes and 50 seconds to complete. Lubomir is a member of the BOINC.SK team.

The progression is written as 139819001440953661+39776662*23#*n for n=0..24. Credits are as follows:

Finder: Steven Schapendonk
Project: PrimeGrid

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Kyle Schwind (kyles) of the United States. Kyle is a member of the Rochester Institute of Technology team.

The AP25 was returned on 9 November 2017 05:59:00 UTC. It was found by an NVIDIA GeForce GTX 980M GPU on an Intel(R) Core(TM) i7-4720HQ CPU @ 2.60GHz running Microsoft Windows 10 Core x64 Edition. It took about 51 minutes and 34 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 was double checked by Bill Brandt-Gasuen (bill brandt-gasuen) and was returned on 10 November 2017 20:32:12 UTC. This task was run on an NVIDIA GeForce GTX 750 Ti GPU on an Intel(R) Xeon(R) CPU E5472 @ 3.00GHz running Microsoft Windows 7 Professional x64 Edition. The double check took about 2 hours, 1 minute and 22 seconds to complete. Bill is a member of the Team ACC - Arthur C Clarke Fans.

The progression is written as 146492329344492673+42846350*23#*n for n=0..24. Credits are as follows:

New AP25

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Tim Terry (TimT) of the United States.

The AP25 was returned on 15 November 2017 15:45:08 UTC. It was found by an NVIDIA GeForce GTX 1060 3 GB GPU on an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz running Microsoft Windows 10 Professional x64 Edition. It took about 41 minutes and 51 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Bryan Little (mfl0p) of the United States and was returned on 15 November 2017 16:30:11 UTC. This task was run on an NVIDIA GeForce GTX 750 Ti GPU on an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 1 hour, 58 minutes and 19 seconds to complete.

The progression is written as 66147818970286411+43305462*23#*n for n=0..24. Credits are as follows:

Finder: Tim Terry
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP25 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

A new AP25 (Arithmetic Progression of 25 primes) has been found. The finder is Jeff Webster (Jeff17) of the United States.

The AP25 was returned on 3 December 2017 3:22:37 UTC. It was found by an NVIDIA GeForce GTX 580 GPU on an Intel(R) Core(TM) i7-2700K CPU @ 3.50GHz running Microsoft Windows 10 Professional x64 Edition. It took about 1 hour, 15 minutes and 44 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP25 task was double checked by Bill Brandt-Gasuen (bill brandt-gasuen) and was returned on 3 December 2017 16:18:45 UTC. This task was run on an NVIDIA GeForce GT 640 GPU on an Intel(R) Xeon(R) CPU E5472 @ 3.00GHz running Microsoft Windows 7 Professional x64 Edition. The double check took about 7 hours, 10 minutes and 6 seconds to complete.

The progression is written as 188705909233852867+44924692*23#*n for n=0..24. Credits are as follows:

Finder: Jeff Webster
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Tom Greer (tng*) of the United States. Tom is a member of the Sicituradastra. team.

This is only the eighth AP26 known to exist, and the fifth found at PrimeGrid.

The AP26 was returned on 30 March 2018 18:04:43 UTC. It was found by an Nvidia GTX 1070 GPU on an Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz running Microsoft Windows 10
Professional x64 Edition. It took about 28 minutes and 3 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Grzegorz Roman Granowski (Grzegorz Roman Granowski) of Poland and was returned on 30 March 2018 19:40:10 UTC. This task was run on an Nvidia GTX 1080 Ti GPU on an AMD Ryzen Threadripper 1950X 16-Core Processor running Microsoft Windows 10 Professional x64 Edition. The double check took about 16 minutes and 18 seconds to complete. Grzegorz is a member of the BOINC@Poland team.

The progression is written as 6197161881651743+55850603*23#*n for n=0..25. Credits are as follows:

Finder: Tom Greer
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Tom Greer (tng*) of the United States. Tom is a member of the Sicituradastra. team.

This is only the ninth AP26 known to exist, and the sixth found at PrimeGrid.

The AP26 was returned on 13 June 2018 19:23:54 UTC. It was found by an Nvidia GTX 1070 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Core x64 Edition. It took about 28 minutes and 12 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Matthew Hill (Mathmusic) of the United States and was returned on 14 June 2018 01:23:59 UTC. This task was run on an AMD CAL Tahiti (3072MB) GPU on an AMD FX(tm)-8350 Eight-Core Processor running Microsoft Windows 10 Professional x64 Edition. The double check took about 2 hours, 54 minutes and 51 seconds to complete. Matthew is a member of the Gridcoin team.

The progression is written as 55837783597462913+62121807*23#*n for n=0..25. Credits are as follows:

Finder: Tom Greer
Project: PrimeGrid

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is user Syracuse University of the United States.

This is only the tenth AP26 known to exist, and the seventh found at PrimeGrid.

The AP26 was returned on 11 August 2018 13:39:18 UTC. It was found by an Nvidia GeForce GTX 1080 Ti GPU on an Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz running Microsoft Windows 10 Enterprise x64 Edition. It took about 19 minutes and 22 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Bruce Webbe (bruce) of the United States and was returned on 12 August 2018 00:23:48 UTC. This task was run on an NVIDIA GeForce GTX 960 (2048MB) GPU on an Intel(R) Core(TM) i7-4790 CPU @ 3.60GHz running Microsoft Windows 10 Core x64 Edition. The double check took about 1 hour, 12 minutes and 49 seconds to complete. Bruce is a member of the Picard team.

The progression is written as 271702189272825977+67515487*23#*n for n=0..25. Credits are as follows:

Finder: User Syracuse University
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Daniel Wimmer (Azmodes) of Austria. Daniel is a member of the Metal Archives team.

This is only the eleventh AP26 known to exist, and the eighth found at PrimeGrid.

The AP26 was returned on 17 November 2018 08:09:54 UTC. It was found by an NVIDIA GeForce RTX 2070 GPU on an AMD Ryzen Threadripper 1950X 16-Core Processor running Microsoft Windows 10 Professional x64 Edition. It took about 16 minutes and 40 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Jaroslav Cerny (Jaroslav) of the Czech Republic and was returned on 17 November 2018 11:19:38 UTC. This task was run on an NVIDIA TITAN V GPU on an Intel(R) Core(TM) i5-2500 CPU @ 3.30GHz running Microsoft Windows 7 Professional x64 Edition. The double check took about 6 minutes and 6 seconds to complete.

The progression is written as 89937610947392099+78413143*23#*n for n=0..25. Credits are as follows:

Finder: Daniel Wimmer
Project: PrimeGrid
Program: AP26

The original AP26 program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little and Iain Bethune.

All builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the AP27. :)

World's First AP27!!!

The first known AP27 (Arithmetic Progression of 27 primes) has been found. The finder is Rob Gahan (Robish) of Ireland. Rob is a member of the Storm team.

This is the first AP27 discovered after PrimeGrid's search of more than three years.

It's also the largest known AP24, AP25 and AP26 (smaller start but larger end than old record).

The AP27 was returned on 23 September 2019 6:25:41 UTC. It was found by an NVIDIA GeForce GTX 1660 Ti GPU on an Intel(R) Core(TM) i5-9400 CPU @ 2.90GHz running Microsoft Windows 10 Professional x64 Edition. It took about 22 minutes and 34 seconds to process the task. Each task tests 100 progression differences of 10 shifts each.

The AP27 task was double checked by Hans Rensen ([DPC] hansR) of the Netherlands and was returned on 23 September 2019 21:31:31 UTC. This task was run on an NVIDIA GeForce RTX 2070 GPU on an Intel(R) Core(TM) i7-6850K CPU @ 3.60GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 13 minutes and 19 seconds to complete. Hans is a member of the Dutch Power Cows team.

The progression is written as 224584605939537911+81292139*23#*n for n=0..26. Credits are as follows:

Finder: Rob Gahan
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Bill Michael.

The AP27 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the ... AP28??? :)

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Brian D. Niegocki (Penguin) of the United States. Brian is a member of the Antarctic Crunchers team.

The AP26 was returned on 9 May 2020 01:48:16 UTC. It was found by an NVIDIA GeForce RTX 2080 GPU on an AMD Ryzen 9 3950X 16-Core Processor running Microsoft Windows 10 Professional x64 Edition.

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Rusty Clark (Gator 1-3) of the United States. Rusty is a member of the U.S. Army team.

The AP26 was returned on 7 November 2020 05:04:22 UTC. It was found by an NVIDIA GeForce GTX 580 GPU on an AMD Phenom(tm) II X2 521 Processor running Microsoft Windows 10 Core x64 Edition. It took about 1 hour 16 minutes and 42 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Steven Schapendonk (HK-Steve) of Switzerland and was returned on 7 November 2020 13:30:03 UTC. This task was run on an NVIDIA GeForce GTX 1080 GPU on an Intel(R) Core(TM) i7-6700K CPU @ 4.00GHz running Microsoft Windows 10 Professional x64 Edition. The double check took about 18 minutes and 8 seconds to complete.

The progression is written as 36583259576579953+201392968*23#*n for n=0..25. Credits are as follows:

Finder: Rusty Clark
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Akihiko Satou (urban_trail) of Japan. Akihiko is a member of the Team 2ch team.

The AP26 was returned on 14 November 2020 00:57:16 UTC. It was found by an NVIDIA GeForce RTX 2060 GPU on an Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz Processor running Microsoft Windows 10 Professional x64 Edition. It took about 19 minutes and 36 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Syracuse University (Syracuse University) of the United States and was returned on 14 November 2020 4:37:27 UTC. This task was run on an NVIDIA Quadro RTX 6000 GPU on an Intel(R) Xeon(R) Gold 6248R CPU @ 3.00GHz Processor running Ubuntu 20.04.1 LTS. The double check took about 7 minutes and 56 seconds to complete.

The progression is written as 433560061205001083+59521353*23#*n for n=0..25. Credits are as follows:

Finder: Akihiko Satou
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Juha Hauhia (KajakDC) of Finland. Juha is a member of the KajakDC team.

The AP26 was returned on 1 March 2021 18:08:11 UTC. It was found by an NVIDIA Tesla K80 GPU on an Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz Processor running Ubuntu 20.04.1 LTS. It took about 1 hour and 45 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Syracuse University (Syracuse University) of the United States and was returned on 1 March 2021 20:03:07 UTC. This task was run on an NVIDIA Quadro RTX 6000 GPU on an Intel(R) Xeon(R) Gold 6248R CPU @ 3.00GHz Processor running Ubuntu 20.04.1 LTS. The double check took about 7 minutes and 53 seconds to complete.

The progression is written as 465808529215122257+72963664*23#*n for n=0..25. Credits are as follows:

Finder: Juha Hauhia
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Hans-Jürgen Bergelt (hans-jürgen [bergelt]). Hans-Jürgen Bergelt is a member of the Bundesstaat Kgr. Sachsen team.

The AP26 was returned on the 17th of July 2022 08:23:04 UTC. It was found by an NVIDIA GeForce RTX 2080 Ti on an Intel(R) Core(TM) i9-9900KS CPU @ 4.00GHz Processor running Microsoft Windows 10 Professional x64 Edition. It took about 7 minutes and 49 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Rusty Clark (Gator 1-3) of the United States and was returned on the 17th of July 2022 08:28:30 UTC. This task was run on an NVIDIA GeForce GTX 1060 3GB on an AMD Athlon(tm) II X2 250u Processor running Microsoft Windows 10 Education x64 Edition. The double check took about 44 minutes and 49 seconds to complete.

The progression is written as 36621451562941339+267460371*23#*n for n=0..25. Credits are as follows:

Finder: Hans-Jürgen Bergelt
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Jeff Thornton (JeffT*) of the United States. Jeff Thornton is a member of the Sicituradastra. team.

The AP26 was returned on the 22nd of January 2023 1:08:51 UTC. It was found by an NVIDIA Quadro K2000 on an Intel(R) Xeon(R) CPU E5-1603 0 @ 2.80GHz running Microsoft Windows 10 Enterprise x64 Edition. It took about 6 hours, 6 minutes and 22 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Jason Sanderson (FreshMD) of Japan and was returned on the 23rd of January 2023 23:30:09 UTC. This task was run on an Apple M1 Processor running Darwin 22.1.0. The double check took about 7 hours, 45 minutes and 18 seconds to complete.

The progression is written as 535466413607576189+72638297*23#*n for n=0..25. Credits are as follows:

Finder: Jeff Thornton

World's Second AP27!!!

The second known AP27 (Arithmetic Progression of 27 primes) has been found. The finder is Tom Greer (tng) of the United States. Tom Greer is a member of the Antarctic Crunchers team.

The AP27 was returned on 26 May 2023 01:04:36 UTC. It was found by an NVIDIA GeForce RTX 4080 on an AMD Ryzen 9 7950X CPU @ 4.50GHz running Microsoft Windows 10 Professional x64 Edition. It took about 4 minutes and 22 seconds to process the task. Each task tests 100 progression differences of 10 shifts each.

The AP27 task was double checked by Vasil Zakiev (zvasi_000) of Russia and was returned on 26 May 2023 01:04:39 UTC. This task was run on an NVIDIA GeForce RTX 4090 on an AMD Ryzen 9 7950X CPU @ 4.50GHz running Microsoft Windows 11 Professional x64 Edition. The double check took about 1 minute and 27 seconds to complete. Vasil Zakiev is a member of the Crystal Dream team.

The progression is written as 277699295941594831+170826477*23#*n for n=0..26. Credits are as follows:

Finder: Tom Greer
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Bill Michael.

The AP27 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations! Best of Luck on the continued search for the ... AP28??? :)

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Brian D. Niegocki (Penguin) of the United States. Brian is a member of the Antarctic Crunchers team.

The AP26 was returned on 28 October 2023 20:48:31 UTC. It was found by an AMD Radeon RX 6800 GPU on an AMD Ryzen 7 5800X3D 8-Core Processor running Microsoft Windows 10 Core x64 Edition. It took about 10 minutes and 47 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Johann Felix ([SG]FX) of Germany and was returned on 29 October 2023 07:57:05 UTC. This task was run on an NVIDIA GeForce RTX 3080 GPU on an Intel(R) Core(TM) i7-1165G7 @ 2.80GHz running Microsoft Windows 11 Core x64 Edition. The double check took about 3 minutes and 46 seconds to complete.

The progression is written as 236832297156314843+287316414*23#*n for n=0..25. Credits are as follows:

Finder: Brian D. Niegocki
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Anthony Templin (10esseeTony) of the United States. Anthony Templin is a member of TeAm AnandTech.

The AP26 was returned on 9 April 2024 3:57:49 UTC. It was found by an NVIDIA GeForce RTX 4090 GPU on an AMD Ryzen 9 5900X 12-Core Processor running Microsoft Windows 10 Enterprise x64 Edition. It took about 1 minute and 33 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Nick Merrylees (Nick) of Australia and was returned on 9 April 2024 3:58:40 UTC. This task was run on an NVIDIA GeForce RTX 3090 GPU on an Intel(R) Core(TM) i9-10980XE CPU @ 3.00GHz Processor running Microsoft Windows 10 Professional x64 Edition. The double check took about 3 minutes and 22 seconds to complete.

The progression is written as 12350473211789819+323868445*23#*n for n=0..25. Credits are as follows:

Finder: Anthony Templin
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Kai Presler (Aperture_Science_Innovators) of Antarctica. Kai Presler is a member of the [H]ard|OCP team.

The AP26 was returned on 15 August 2024 13:28:14 UTC. It was found by an NVIDIA GeForce RTX 4090 GPU on an AMD EPYC 7H12 64-Core Processor running Linux Mint 21.1. It took about 1 minute and 26 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Vaughan Davies (vaughan) of Australia and was returned on 15 August 2024 13:55:55 UTC. This task was run on an NVIDIA Tesla G4 GPU on an Intel(R) Xeon(R) CPU @ 2.30GHz Processor running Ubuntu 20.04.4 LTS. The double check took about 17 minutes and 14 seconds to complete.

The progression is written as 402905241129295973+303960530*23#*n for n=0..25. Credits are as follows:

Finder: Kai Presler
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Kai Presler (Aperture_Science_Innovators) of Antarctica. Kai Presler is a member of the [H]ard|OCP team.

The AP26 was returned on 2 September 2024 20:26:07 UTC. It was found by an NVIDIA GeForce RTX 4090 GPU on an AMD Ryzen 9 7950X 16-Core Processor running Microsoft Windows 10 Professional x64 Edition. It took about 1 minute and 26 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Heinrich Podsada (PoHeDa) of Germany and was returned on 2 September 2024 23:51:14 UTC. This task was run on an NVIDIA GeForce RTX 3070 GPU on an AMD Ryzen 9 5950X 16-Core Processor running Microsoft Windows 11 Professional x64 Edition. The double check took about 5 minutes and 31 seconds to complete.

The progression is written as 157728788021945501+369205110*23#*n for n=0..25. Credits are as follows:

Finder: Kai Presler
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Norman Luhn's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Ian Johns (ian) of the United Kingdom.

The AP26 was returned on 3 February 2025 2:30:00 UTC. It was found by an NVIDIA GeForce RTX 4060 Ti GPU on an 13th Gen Intel(R) Core(TM) i5-13600KF Processor running Microsoft Windows 11 Professional x64 Edition. It took about 5 minutes and 1 second to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Milan Fňašek (RNDr. MF1) of the Czech Republic and was returned on 3 February 2025 15:55:55 UTC. This task was run on an NVIDIA GeForce RTX 3070 GPU on an 12th Gen Intel(R) Core(TM) i7-12700F Processor running Microsoft Windows 10 Professional x64 Edition. The double check took about 5 minutes and 30 seconds to complete.

The progression is written as 784626811797008861+131109295*23#*n for n=0..25. Credits are as follows:

Finder: Ian Johns
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Norman Luhn's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Kai Presler (Aperture_Science_Innovators) of Australia. Kai Presler is a member of the [H]ard|OCP team.

The AP26 was returned on 19 August 2025 2:39:26 UTC. It was found by an NVIDIA GeForce RTX 4090 GPU on an AMD Ryzen 9 9950X 16-Core Processor running Linux Mint 21.3. It took about 1 minute and 27 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Samuel Williams (sam6861) of the United States and was returned on 19 August 2025 2:52:20 UTC. This task was run on a CAL AMD Radeon RX 6600 XT GPU on an AMD Ryzen 9 5950X 16-Core Processor running Microsoft Windows 10 Core x64 Edition. The double check took about 11 minutes and 42 seconds to complete.

The progression is written as 508726054362132053+324716842*23#*n for n=0..25. Credits are as follows:

Finder: Kai Presler
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Norman Luhn's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Jacques Molné (Elzeard BOUFFIER) of Canada. Jacques Molné is a member of the Canada team.

The AP26 was returned on 12 March 2026 23:52:21 UTC. It was found by an NVIDIA GeForce RTX 4070 Ti GPU on an AMD Ryzen Threadripper 1950X 16-Core Processor running Ubuntu 25.10. It took about 2 minutes and 50 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by an anonymous user and was returned on 13 March 2026 6:50:02 UTC. This task was run on an NVIDIA GeForce RTX 2060 GPU on an Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz Processor running Microsoft Windows 10 Professional x64 Edition. The double check took about 19 minutes and 2 seconds to complete.

The progression is written as 1059580293805246783+150452799*23#*n for n=0..25. Credits are as follows:

Finder: Jacques Molné
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Norman Luhn's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Kai Presler (Aperture_Science_Innovators) of Australia. Kai Presler is a member of the [H]ard|OCP team.

The AP26 was returned on 26 July 2026 02:50:56 UTC. It was found by an NVIDIA GeForce RTX 4080 SUPER GPU on an AMD Ryzen 9 7950X 16-Core Processor running Microsoft Windows 10 Professional x64 Edition. It took about 2 minutes and 11 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Allen Paschke (Allen Paschke (aka Santa)) of Antarctica and was returned on 26 July 2026 3:29:34 UTC. This task was run on an NVIDIA GeForce RTX 4060 Laptop GPU on an AMD Ryzen 7 8845HS Processor running Microsoft Windows 11 Core x64 Edition. The double check took about 10 minutes and 25 seconds to complete.

The progression is written as 803639231100017029+317247993*23#*n for n=0..25. Credits are as follows:

Finder: Kai Presler
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Norman Luhn's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Vladislav Ketamino (KetamiNO [YouTube]) of Ukraine. Vladislav Ketamino is a member of the Ukraine team.

The AP26 was returned on 6 September 2026 20:43:17 UTC. It was found by an NVIDIA GeForce RTX 4070 SUPER GPU on an Intel(R) Xeon(R) CPU E5-2673 v4 @ 2.30GHz Processor running Ubuntu 24.04.4 LTS. It took about 4 minutes and 51 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by tianyin of China and was returned on 6 September 2026 20:48:31 UTC. This task was run on an NVIDIA GeForce RTX 3080 GPU on an Intel(R) Xeon(R) CPU E5-2697 v3 @ 2.60GHz Processor running Microsoft Windows 10 Education x64 Edition. The double check took about 3 minutes and 53 seconds to complete.

The progression is written as 1210688189842677941+110655252*23#*n for n=0..25. Credits are as follows:

Finder: Vladislav Ketamino
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Norman Luhn's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!
