a new one to start off GFN11's

Congratulations on the new factors Batalov! Surely you will be getting more soon. It seems that I'm missing GFN7 factor from my collection. Since I don't have a GPU in use, I'll shoot some candidates with ECM.

Indeed, ECM ...or P1...
Code:
7^4194304+1 has a factor: 20827885658921521643521 (P1, B1=160000, B2=16000000, E=12) [mprime] 620719363061235*2^25+1 is a Factor of GF(22,7) !!!! (0.000000 seconds) ? factor(208278856589215216435211)~ [ 2 3 5 37 53 601 3901301] [25 3 1 1 1 1 1] Code:
(2401^1048576+1)/2/20827885658921521643521 is not prime. RES64: 74CF355631DC5DD7. We8: A1746598,00000000 #prime95/mprime doesn't "show" parentheses in the outout, but we know what "it meant to say" Last fiddled with by Batalov on 20161106 at 23:13 Reason: cofactor is composite

Finally, after a week of no factors, two ... next to each other!
Code:

I don't know if this thread is dedicated to the "new" 7/11 generalized Fermat factors.
If this is the case, then you can use the thread http://www.mersenneforum.org/showthread.php?t=21986 to send your "classsic" gfn/xGF factors else 20085603*2^14098+1 is a Factor of xGF(14097,9,5)!!!! 21704897*2^14499+1 is a Factor of xGF(14498,9,5)!!!! 28371113*2^14393+1 is a Factor of xGF(14392,7,2)!!!!
