Nice find! How many curves did you run? (Maybe I'm looking in the wrong places, but I don't see curve counts for the results line with factors found)

According to the PrimeNet results, storm5510 ran 6 curves and then found this factor. 424 other curves had been run by other users prior to finding the factor.

The default automatic reservation from PrimeNet is 7 curves for ECM.

My largest-ever find was 39 digits. As a general rule, I don't post anything now less then 30 digits, but it had been a while since I had posted anything at all, so I thought, why not...

OK I lied just a bit (not Donaldish).

The factors are reported in a row by misfit; but I still got 3 out of 8 attempts and 2 were consecutive

I know, it is a composite but still
M32148013 has a 171.369-bit (52-digit) composite (P26+P27) factor: 3866049125437654294832342492322663453310186293606097 (P-1,B1=500000,B2=15000000,E=12)

Impressive! Really hope I can get a fat composite factor someday too. (If the probability of a factor within a set of P-1 bounds is independent of the presence of another factor, then that day could be only a few months away,)
