[QUOTE=lycorn;502672]I did notice it too.
The sub 10K range is one step closer to be cleared (which doesn´t necessarily mean it will ever be...) :smile:

M921001 has a factor.
It was found by ECM, using B1=250000, B2=25000000. Given that the size of the factor is just over 78 bits, it was missed by the previous trial @ B1=50000. It took 115 curves, tho. Oh well, one down.

It is a 24-digit factor. A full t25 ECM has about 25% probability of missing such a factor (25% is a ballpark -- I don't know the exact probability).

You´ve been finding a fair amount of ECM factors for small exponents lately :bow:. I have some experience in working in those small ranges, so I truly appreciate your effort. How many cores have you assigned?
