I also noticed, that n^41+1 is much less factored, only up to n=1100 are all numbers FF. The smallest n been unfactored is n=1109 with C122 cofactor.

Between n=1000 and n=1500 are 18 numbers not fully factored.

I´ll at least pretest these numbers and list them here. Please note: Slow progress.
These are all SNFS numbers, so a quadcore could knock them all out in a couple of hours ?
