New AP26!!!
A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Takeshi Nakamura (kuroganet) 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 E52667 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:

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:

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) i54570S 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) i37100U 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 Bryan Little (mfl0p) of the United States.
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) i77700K 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 E52660 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:

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) i36100 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.

New AP25
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) i72700K 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 BrandtGasuen (bill brandtgasuen) 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.
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. :)

As of 2018, AP25 discoveries will no longer be announced here. The threshold for qualifying for an announcement is now an AP26 or longer.
____________
Please do not PM me with support questions. Ask on the forums instead. Thank you!
My lucky number is 75898^{524288}+1

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 E52680 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) i74790 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:

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) i59400 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) i76850K 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??? :)
