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!
