Factoring Mersenne numbers

ECM on 2^P-1, P > 10000

Curve counts in these tables assume B2=100*B1. This is the default for prime95. For maximum throughput on the smaller exponents listed, you should use GMP-ECM for stage 2 (and report an adjusted number of curves for updating this table).

Mersenne Numbers, no known factors
