Updates for 2016
The history page has been updated with new limits for k.
Also, a new slot has been added for M49: its ks are actually under sieve (it will stop at 100T) It seems that I am the one working on this project, and looking for a big nonMersenne prime... Luigi

most of the k found on the double mersenne page for MM49 trivially factor. Or did I made a mistake?

true but I don't see it as complete waste ( not that I'm important I mainly just look over half the subforums over the course of a day) because $(2kp1)^{2a}$ will be eliminate some composites if they still exist in the 2kp+1 values as it expands to $(4*p^2*k^2  4*p*k + 1)^a = (2(pk^2+2k)p+1)^a$
