I would soon like to reserve another range of 40k or more.

(At the moment only 2740-2750 available)

Congratulations, indeed! It's definitely about time for a prime on this k...600K-2.7M is enormous as far as primeless gaps go.

unconnected, great !!

Congratulations!

Retep 2010-10-18 15:26

I'm releasing 2740-2820.

Congratulations @ unconnected we finally found the prime.

Could someone explain why Prime95 was in the prover code? I thought it was only used for testing mersenne numbers (LL), not for k*2^n-1 numbers (LLR).
