Different animal. I know about extra checks when residues don't match. I'm speaking of triple or higher checks where all residues agree. The only reason to do those other than the exponents that have only 16 bit residues is to check for cheating. If those kinds of checks need to be done, they ought to be done with intelligence, not by random poaching.[snip]From: "Mary K. Conner" <[EMAIL PROTECTED]> Subject: Re: Mersenne: Re: Mersenne Digest V1 #1036[snip]Actually the project *does* deliberately do a fair number of triple checks. You just see them as double checks that's all. Why? where the residue bits returned from the first and second, do not match.There are plenty of triple checks that happen accidentally. There is no GIMPS need to do some on purpose, especially to the detriment of a participant that is following the rules. If someone feels a personal need to do triple checks, they should do them on exponents that are already double checked.
