Maybe my day was super long because the second time had barely arrived - M168830323


M168,*3*,*23 survivors at the moment:

005, 074
128, 131, 168, 191, 195
233, 236, 275
332, 363
476, 483
501, 527, 593
609, 612, 644, 666, 681, 693, 699
702, 719, 758, 765, 768, 785
813, 825, 830, 846
906, 908, 911, 921, 941, 948, 971, 989

The quadrupler that I'll specifically working on: M168931123, M168932123, M168934123, M168937123

I don't think SRBase will run P-1 factoring across the large range of exponents, the several Nvidia Geforce 3090 will run TF ultra fast, but P-1 requires AMD Threadripper 5970X or at least 5960X to advance that rapidly.

The trial factoring bits are mostly up to 2^76 in the M116M range, but P-1 are missing - https://www.mersenne.org/report_expo...6844000&full=1

UncWilly previously mentioned about a model that hinted a Mersenne Prime may be hidden within M116M or M117M ranges.

The statistics at this page
https://www.mersenne.org/report_top_500/
would indicate that SRBase, (along with a 14 others in the top 500), do 100% trial factoring.

The majority (perhaps 80%???) of exponents below 105.2 million have already had the P-1 done. As exponents get larger, less and less have had any P-1 factoring.
