P+1 testing
 

Is there a posting specifically about this type of work?
If so can someone direct me there please, thanks

Do you mean [URL="https://primes.utm.edu/prove/prove3_2.html"]N+1 primality proving method[/URL] or [URL="https://en.wikipedia.org/wiki/Williams%27s_p_%2B_1_algorithm"]P+1 integer factorization method[/URL]?

I do not know either of these.

In the list of work types:

P+1 Factoring

Here are some discussion and explanations of P+1:

and in the 30.4/30.5/30.6 thread from post #150 and onwards when the P+1 feature was released in version 30.6:

This is indeed the P+1 integer factorization method, click the link in my post #2 to see what is this

OK, but how do I run P+1 using mprime?

Not recommended right now. I'd use ECM and version 30.9. Someday I may get around to polynomial stage 2 for P+1 factoring.

For background and perhaps starting the learning curve before P+1 is perhaps improved someday, there is [URL]https://mersenneforum.org/showthread.php?t=26750[/URL] and bits of [URL]https://mersenneforum.org/showthread.php?t=24607[/URL]. P+1 is not a part of the usual progression of a prime exponent while searching for new Mersenne primes, so is neither automatically assigned, nor manually reserved at [URL]https://www.mersenne.org/manual_assignment/[/URL]. So, worktodo entries must be constructed by the user AFAIK. See also the "New features in Version 30.6 of prime95.exe" section in mprime's whatsnew.txt distributed with the program.
