It certainly did help me! So, why are only certain ranges listed on the PrimeNet status page? For example, from time to time, their front page has failed to list the 'cutting edge' of PrimeNet factoring assignments. As a somewhat related question, when an apparent double-checking milestone i

Hi again, I looked at the MS site with its dropdown menus.  It was far more javascript than I want to wade through.  So I've come up with a simpler header that incorporates a menu.  Let me know if you like this (especially as compared to the more traditional menu on the side).  It does get us mor

Mersenne: Prime 95 & Base 3

How hard would it be to modify the source code of Prime 95 to calculate a base 3 number mod a prime number and then square and mod the result? Are there any programs along this line? Dan
