Larry, you had one in 761-763:

20625*2^762932-1 (L260)

We just got so accustomed to say "no primes" :smile:

756-760 complete - 1 prime
taking 766-770

Yes, thanks Kosmaj! :smile:

oh, btw, I took 764-766 (2 files) but the main page only says 764-765. Thankfully, pb386 figured it out and took from 766 on.

While I'm here, 763-764 complete, no primes.

New test files added, up to 790k.

Larry, sorry about that.
