Nice work. I can't help but think that you may have been inspired by Red Dwarf psi-moon episode. But anyways - good ideas are universal. RIP 3*2^n+1 and 3*2^n-1 candidates below 3 million decimal digits!

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.

This is excellently going off topic from primes. Rimmer is on a moon that terra-forms (and psycho-forms?) from his personality.

You wanted the episode - I just looked at my TVR - all I can get is MCMXCII which is 1992?

I looked at the start again - the episode is called Terrorform.

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!

I was quite surprised to find that posting in 2013 referring to red dwarf.
After a few moments of what the? I do remember it.

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:
