That may help. I'll try it.

Maybe it's got a problem with the exponent P=103695649.

2004109083829816426995592902 = 2 * 3 * 281 * 29917 * 47269 * 8106041 * 103695649, so the biggest factor is 103695649, the exponent, which is bigger than B2=20264000.

Is it possible it's not accounting for the special form of Mersenne factors, which allows ignoring P as a factor of Q-1 (Q is the factor found) and only using the general rules for factors found by the P-1 method?

That's probably it.

M1001159 has a 120.912-bit (37-digit) factor: 2500439903769890259112379635985290039 (P-1,B1=10000000,B2=1110000000)

Is it Christmas already? This one should come in at about 365th place.

No, no, no, I have no budget for christmass right now. So it is NOT christmass. At least for another 6 month.

You have bet my best. I am in the 120 bit club too. Very nice catch.

M23554211 has a 114.027-bit (35-digit) factor: 21164767805799094411604254592575543 (P-1,B1=1200000,B2=79200000)
I also have a near Christmass time

We found both an 98.x and 101.x bits factors in 35.1M range, what's worth mentioning them is the fact they were both found in a row, one after the other, and both found [U]in stage 1[/U] (!)
They are not sync'd on James' site yet, but they are indeed very smooth!

Your 98.x factor directs to 83.x factor and 101.x factor directs to 98.x factor.

Fixed, thank you very much! (I didn't edit the quote in your post, only my post). I got lost in so many factors and links. But in this case, the 101 is not anymore "smooth". My mistake. As they were not yet on mersenne.ca at the time, I wrongly remembered their size (which is displayed when reporting), and I assumed the 101 was the smooth one (the "smoothness" is deduced from the amount of credit given, you don't need to do any calculation or to see the k value to know your factor is very smooth, hehe).

Therefore, to repair the damage, take this new 115 bits guy here...

Um, I don't know how to check the result. I just report what the screen and results file shows me.
