I guess we just need to look at exponents in the form 410xx441 to find big P-1 factors? :)

I am still continuing to beat you all with.... [URL="https://www.mersenne.org/report_exponent/?exp_lo=103901689&full=1"]composite factors[/URL], haha.
But I won't be picky about the double amount of credit :razz:

Feel free to come back to "the dark side" when you get bored.

The k is very low. it would have been found with a B1 @ 35111

UID: Jwb52z/Clay, M100111807 has a factor: 5497876794406428536190503 (P-1, B1=820000),

82.185 bits.

[QUOTE=Uncwilly;555649]Ryan found a 208 bit factor:[/QUOTE]
And another 200+ digit factor has arrived thanks to Ryan:
M[M]2083[/M] has a factor: [C]4188332412064506725391133958916461731585439326430544722593471[/C]
That brings it to 199 digits of known factors out of 628 digits. A known forumite is doing the PRP-CF.

But but but... factordb would quasi instantly tell you , for a Mp of this size. up to about M(8k) or M(9k)

PrimeNet assigns it out anyway. The PRP will get done and a cert will get run soon.
