Thanks, and congrats to all on this unexpected holiday treat!
I attached the log files from the Tesla V100 and MLucas run if anyone is interested.

It was also out early on this site, they picked it up from primzahlen.de:
https://www.mathematik.de/dmv-blog/2...mzahl-entdeckt

I was wondering if anyone found it early but did not say in this thread to avoid making it more public?

Welcome to the forum.

Not all of us are that deep in the math. I never took calculus.

Your find has all sorts of fun things about it. Nearly a year since the last one (which is lower than our norm.) It also is near the end of the wave for the first time checks (we need less than 115 to check in to have all the numbers up to the new prime checked, a record for us.) It is also closer to the recent ones than many would have thought (randomness is clumpy.) And you hit the George is on vacation thing (a few others have occurred around his vacations.)

Your interim Prime95 residues don't match ATH's CUDALucas interim residues.

It may be that you have to post the ...0002 residues rather than the ...0000 residues, or at least that was the case for comparing mprime residues with Mlucas.

Usually you need to use the +2 residue from Prime95 to match the one from CUDALucas and Mlucas, because Prime95 starts from S2 and end in Sp, while the others run from S0 to Sp-2. But it seems the server actually stores the +2 residue, because they do match:

The way GIMPS arrived at the primality is what is recorded. There is no need to erase those results, even if, as you noted, they are meaningless now. Otherwise at each higher level of TF the previous work should be erased and replaced by "no factor to" the new level.
