Did you fiddle with mmff to extend range? If not it only goes to 188 bit factors which is k=5.5e11 for n=149, k=1.1e12 for n=148..... k=7e13 for n=142.

 2012-09-30, 07:00 #42 Batalov     "Serge" Mar 2008 Phi(4,2^7658614+1)/2 3·7·479 Posts I noticed that later. (It depends on the k value; for lower k ranges, it would have run). I am running the early 140s now. I will probably fiddle, later. (Now that my hands are untied from PE 396, heh, heh, nice one, btw..!) The same limit kicks in for the mmff-gfn and I did want to extend the upper limit for both. The main driver of the probability of success is simply ~ 1/k !* (~ 1/k * 1/(ln k + N ln 2), but the last part is so-o-o-o flat), so getting to as low k as possible is desirable. ;-) *! is not the factorial sign, surely Last fiddled with by Batalov on 2012-09-30 at 07:02 Reason: 1/k! would have been silly
