Hi,

I received an email indicating my computer, which is assigned to the AP27 project, has found two unique Arithmetic Progression of primes of length 20. And since primes found in this sub-project are not large enough to report to the Top 5000 Primes List, my AP20 sequence will be visible immediately....

28 Jul 2018 | 15:42:01 UTC: 311639370756505291+66124273*23#*n for n=0..19
28 Jul 2018 | 20:27:02 UTC: 20196677993854777+66261997*23#*n for n=0..19


Thanks,

They are 16 or 17 digits long. So tiny compared to what we search for, but what makes these primes special is that there are 20 of them with a common difference between each!

If you go to Your account an then click on AP26/AP27 tasks (view detailed statistics), you'll see all the AP sequences you have found.
Just click on any of them to see all the primes in that AP sequence.
