well we know if p and 2p+1 are both primes of form 4x+3 then 2p+1 divides Mp so that's a slight skew in the mod 12 version (potentially has an affect on primes of form 11 mod 12 as that's the intersection of primes of form 4x+3 and 6y+5 that are both required, so that 2p+1 could also be prime). not sure of any other rules and their effects.

There was a suggestion circled around to split all the Conjecture talk in a separate thread.
(And perhaps "the size of the kit" comparisons in the other. )

For dyslexics, right (or correct) and wrong, left and write et al are a very complex and difficult subject.
It all depends on the frame of reference and the context... We have a lot of trouble with mirrored frames of reference, for example. "Dyslexics of the world, untie!

It's only here because masser gave binarybased histogram bins for Mersenne primes, which led me to post about hexadecimal bins and hexadecimal final digits, and one thing led to another.
