__HRB__ Dec 2008 Boycotting the Soapbox 1320₈ Posts	100M-digit n/k pairs If you had a program that could complete a primality-test for a 100M-digit candidate of the form k2^n+/-1 in ~6 months on a 3.2Ghz quad-core machine, which k and n would you choose? EDIT: There is a bonus if k has a 2^24th root (mod 2^64-2^32+1) Last fiddled with by __HRB__ on 2010-05-22 at 01:24*
