Awesome! I received your certificate, and everything appears to be in good shape.

So what do we do for entertainment now?

Find the last prime.

Congrats Engracio

!

That was your first multicore certificate.

You could.

Thanks Norman for the help. I wonder how long before we all get knocked off the top-20 list.

Like Norman I think I will take a break from Primo for a while. It is a long slog this last one. Until we get better technology I will just have to try to find the last prime for FOB and hopefully another k with SOB.

Thanks to Justin (enderak) who has now double-checked the sequences for 75353 and 28433, and helped me finish double-checking the sequence for 60451. Matching residues now proves that 2⁹⁸³⁶²⁰+60451, 2^1518191+75353, and 2^2249255+28433 are the smallest probable primes of their respective sequences. Only the three sequences for 2131, 41693, and of course, 40291 are not completely double-checked now. We found a couple of missing residues, but only two actual errors in the first time prp tests, both for the 28433 sequence at exponents greater than 2 million. I am hoping that in a couple of years, GPU processing may help speed up the double-checking for these last three sequences, but the results so far do tend to confirm a low error rate in general for Five or Bust work. Good work, everyone, and thanks again, Justin!

I have ever trouble with "sourceforge.net".

Thanks !

This thread is enough.
