It's a milestone not a tombstone! LOL. Viva 321.

Please elucidate about the Red Dwarf episode. I can find only parts of it on YouTube.

Congrats to PrimeGrid's crunchers for double checking all 3*2^n-1 and 3*2^n+1 up to exponent 11 million. The former should get a new prime with an exponent less than 12 million!

We've now tested and double-checked all candidates through 15 million bits--the last candidate finished DCing less than a day before the SoB double-check ended. On to 16M!

Double-checked through 15.5 million bits. This last half-million went much faster than usual thanks to the ARPANET challenge in October.

It's been a while.


There were some fantastic 18 months from January 2014 through June 2015 where four 321 finds were done. Since then, no more finds.

When will the next one occur? Links:
