3607 is down
 

I thought that sub 10K are impossible to factor, but here it is:
"M3607 has a factor 162160065980366340636967897279169391509046358190713" (~167 bits). Unfortunately, the cofactor is not PRP :smile:.

Great shot!

Funny enough, in the "history" section of the report, there´s no reference to the bounds used nor the number of curves run.
Did you use a B1=1.1e8?

Stock bounds for sure (B1=1.1e8). I do not have access to the machine right now (to pull out the log), but it is probably couple of thousand curves.

Fantastic result :bow:

I'm trying my luck down in the 4k range, you never know....

Also digging that area, just slightly higher - 6 and 8k. Something is lurking up there... :rolleyes:

Nice find! You don't get those every day!

Whoaaa! Great one! 167 bits, hey don't come easy..

Nice work. :bow:
