In my book any non-Mersenne prime over 1999,999 digits is awesome!:buddy::toot::rgerbicz:

[QUOTE=storm5510;527803][U]Question[/U]: What are these being ran with to get this format? It looks fascinating. :smile:[/QUOTE]

Sorry for overlooking your question for so long. We run LLR to test k*2^n-1 or k*2^n+1 formats (and quite a few others). If LLR doesn't handle it, PFGW does.

Also, 231*2^2335281-1 is prime! 702992 digits.
