I just received this message from Payam Samidoost:
"79425*2^100520+1 is a Factor of F100518!!!! Oct 22, 2014
Sieved by Fougeron's FermFact, found as a prime using PennĂ©'s LLR and revealed as a Fermat factor by Fougeron's PFGW.
I was expecting some new xGF divisors first, but luckily the very first was a Fermat divisor!
I am checking all 5 digit k's for 100000<n<=100999. I have already verified Batalov's 10000<k<40000. I will continue with 101000<n<=101999 then 102000<n<=102999 and so on."
