The search is over!

After a three year effort, the first ever AP27 (Arithmetic Progression of 27 primes) has been found:

224584605939537911+81292139*23#*n for n=0..26

The AP27 was found by Rob Gahan (Robish) of Ireland. The discovery was made on 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. Rob is a member of the Storm team.

Congratulations to everyone who participated in the AP27 search! It has been a very challenging and rewarding project.

For more information, please see the official announcement or our AP27 forums.
