A factor of a double Mersenne number MMp has form 2*k*Mp+1. We are testing the small k.
All k < 10,000 have been tested up to 20G except for MM34 ad MM35 where k < 500,000.
On this page we insert the K values of factors Q = 2 * k * Mp + 1 proven composite after being sieved,
and for this reason not suitable of being proper factors of MMp.
