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!

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.
However, it makes zero sense :)

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:

Done through 16M bits!

Still no new primes since 3*2^11895718-1. At this point one would expect about 2.5 new primes since then, with over a 90% chance of at least one. As for the future, there should be about 1 prime between n=16M and 18M.

We've now finished testing all candidates through 16.5M bits, and the leading edge is just over 5M digits. Two exciting things have happened since the last update: first, we started using Pavel Atnashev's LLR2, which effectively doubles the speed of the search. And second, the drought finally ended with Scott Brown's 4,939,547-digit prime 3*2^16408818+1!
