My ECM record beaten!

Hey guys! Attention. I have a NEW record for my ECM factors. This one is a mere 2 times larger than my previous record. So, here it is:

F(49) c229=2995024595046490939332597113516148569*c192

This is the 6th factor of F(49), and also the largest. :)

details of the factorization:

b1=3000000

b2=5706890290

sigma=3278406897

If F(49) is to be completely factored, extra ecm work will have to be done on the c192 cofactor as it is still too large for a gnfs factorization on a single computer in a reasonable timing.
