I just saved my first 2 LL tests near the wavefront. (GPU272)

k=2^2 x 13 x 61 x 3301 x 24001 x 2033287 x !702,642,949!
I *THINK* this is a B-S factor since it was found with B1=10M B2=250M E=12
109.14 bits :) My first above 100 bits!

I know it is useless but still
M8803577 completed P-1, B1=105000, B2=1916250, E=6
P-1 found a factor in stage #1, B1=105000.
UID: firejuggler, M8803573 has a factor: 589495498411470532681
k=2^2*3*5*2857*4831*40429

last pm1 was @ B1=40000, B2=B1, so it didn't need 'much' more to get it

Wow, that wasn't missed by much at all the first time!

M601983997 has a factor: 60136908979114760311 (65.705 bits)
M601986001 has a factor: 41955526838838866881 (65.185 bits)

Both were found by trial factoring using Prime 95. However, the interesting part is that both had been TFed using mfakto up to 67 bits, but reported no factors. It leads me to think is it necessary to double check trial factoring results?

It depends. If it is a reproducible error (i.e. bug) in mfakto, then maybe. If it is a hardware issue, then no. AFAICT, "gpu 2 72" has been finding the expected number of factors.

So someone should rerun those with mfakto, but I'd only be worried if they were different users.
