You are right. I'm confused, too. I don't have the line from results.txt anymore, but mersenne.ca (https://www.mersenne.ca/exponent/70553939) definitely tells me that it was found with e=12. I can't...

Yes, it did. I tried to understand why this large factor 195509617 of k for my factor of M70553939 (https://www.mersenne.ca/exponent/70553939) has been found with e=12 Brent-Suyama and a B2 of only...

Yes, but I was comparing "spot" prices to my power costs and still twice as much as I pay for my power. Don't forget all those virtualization AWS does has overhead, too. The most ridiculous...

Ok, this was not obvious to me. I always assumed it would calculate 3^{\frac{2^n-1}{p}} \text{ mod } \frac{2^n-1}{p} instead (assuming p is one or more factor). Then the residues would be different.

I used mprime and the residue B786DF1732AE7343 is the one which mprime reported in the results.json.txt. I filed a bug in the Primenet section (https://mersenneforum.org/showthread.php?t=26448).

C-PRP residue identical with different factors

Hi, yesterday I did just for fun a P-1 test for the small, already factored number M3331331 (https://www.mersenne.org/report_exponent/?exp_lo=3331331&full=1). This number had one known factor and two...

AWS is too expensive (for me)

I have done some experimenting with AWS (and tested a DC number), but even in Germany with high power costs (30ct/kWh) it is usually cheaper to run it on the hardware one already owns if you have the...

Poaching when Trial Factoring

I have a pretty crappy GPU in my laptop, but at least I can run mfaktc on it, when my laptop is running and connected to the power. This will contribute quite irregularly, sometimes, there might...

Hihi, thanks for that! My laptop GPU is too crappy for this bitlevels. However, I assume your chances for success are quite low because of the large P-1 and the ECM curves I already ran. I won't...

This stupid number doesn't want to reveal its factors, so my quest will stop after a lot of TF and P-1 and half of t25.

Yes, but it doesn't show up on the top right in "Latest Primenet details". It isn't important, but to me it looks like a bug. And I assume there are not many numbers which have both LL/DC and PRP, so...

PRP for exponent not shown

M20825573 (https://www.mersenne.ca/exponent/20825573) does not show my (unnecessary) PRP run, which I reported a few days ago. There seems to be a bug. Please compare the output of mersenne.ca with...

PRP for F33?

Hi,
first of all, sorry if this is a noob question. I am wondering why noone has proven the (non-)primality of F33 with PRP testing. It will be a huge task, but should be doable, shouldn't it?
