On 5 September 2017, 08:23:41 UTC, PrimeGrid’s AP27 Search (Arithmetic Progression of 27 primes) found the progression of 26 primes:
48277590120607451+37835074*23#*n for n=0..25
It is the 7th known AP26 known to exist, and the fourth found at PrimeGrid.
The discovery was made by Bruce E. Slade (Renix1943) of the United States using a NVIDIA GTX 970 GPU in an Intel(R) Core(TM) i3-6100 @ 3.70GHz CPU with 16GB RAM, running Microsoft Windows 10 Core Edition. This computer took about 41 minutes to process the task (each task tests 100 progression differences of 10 shifts each). Bruce is a member of the Aggie The Pew team.
The progression was verified on 5 September 2017 19:34:24 UTC, by Axel Schneider (axels) of Germany using an NVIDIA GTX 680 GPU on an Intel(R) Core(TM)2 Quad Q9400 CPU @ 2.66GHz with 8GB RAM running Microsoft Windows 7 Home Premium Edition. This computer took about 2 hours 6 minutes to process the task. Axel is a member of the SETI.Germany team.
