For quality assurance (QA) purposes, a stage-1 P-1 test was performed on M726064763 without excluding in quotation marks the 12 known factors.
The result is a 145-digit 481-bit composite factor which is a product of 9 out of said 12 known factors.
Code:

Perhaps more P-1 tests could factor at least one of the remaining unfactored Mersenne numbers for small exponents:
M1277, M1619, M1753, M2267, M2273, M2423, M2521, M2713, M2719, M2851, M3049, M3673, M3691, M3847, M3881, M3919,...

What exactly do you propose to run these with?

My submitted P-1 tests on M1277 and M1619 were performed with Intel Core i7-7700 @ 3.60GHz and just 16GB RAM. Let's assume that many users have much better computers and more RAM.

I have the exact same hardware. I should have phrased my question differently. What software, I should have asked? Prime95, gpuowl, Yafu, for example.

I did P-1 on M1277 with B1=1012 and B2=2.35*1017 with GMP-ECM 7.5 years ago back in January 2015, and I wouldn't be surprised if other people went even further.

I did not turn it into primenet because it would just have broken the Ghz-Days system with a gazillion Ghz-Days.

I also did 2 x P+1 runs on M1277 with B1=5.1*1011 and B2=5.4*1016 and B2=7.8*1016.

I am using Prime 95 version P95v30.8b15 for P-1 tests while waiting in anticipation for a stable version of P95v30.9 to run ECM more efficiently.

That is correct, the Ghz-Days statistics for "Totals Overall" is disproportionate now.

I looked at the details for M1277 a while back and saw where someone had ran a really large P-1. I did not pay attention to when it was completed. If a person includes all the ECM data, it takes a while for it to come up on Primenet. M1277 goes way beyond a "recreational test!"

This one is for the less ambitious lads and gals, a notch below the 332,192,809 100-MDigit threshold, please consider the DC of M332192779.

I'm wondering why there was a need to recheck the trial factoring bits of M161803403 from 273 to 278. Kriesel's hardware is very reliable, there wouldn't have been any errors.
