[QUOTE=petrw1;610015]Still working on P-1 here?[/QUOTE]

Maybe we should make this thread unsticky and the new thread 'Let's optimize...' on P-1 sticky..

And it shall be done...

[QUOTE=petrw1;609517]TF found 1 factor.
1 more to go....anyone want to do P-1 here?
There a couple exponents with no P-1 and lots with only B1.[/QUOTE]

There are still 2000 unfactored in 108.9M so far, with 1 more to go. Is there anyone who wants to complete this range?

[QUOTE=ATH;604165]
As you said the "title project" will finish on its own over time, current status: 20,422,960 unfactored exponents
Based on the speed of the last 365 days with 201558 factors found, ETA to 20M unfactored is 766 days: ~ May 2024.[/QUOTE]

Now the number has reached 20,348,514. That's 74,446 newly-factored exponents in 129 days, i.e. 577 per day. This speed is faster than your data (552 per day). ETA is now March 2024 from my data.
And I think there will be further increase in our speed since the release of v30.8 (faster P-1) and v30.9 (faster ECM), so I think it is possible that the ultimate goal can be reached before the new year of 2024.

Actually the vast majority of factors are found with TF with programs using GPU (so Prime95 is not relevant for the task of reducing the number you cite above to 20,000,000). The most prolific contributor is srbase, which is a team of about 100 members using their GPU.

P-1 found a factor in stage #2, B1=859433, B2=148052100.
M108906529 has a factor: 4081181996838659866466757911 (P-1, B1=859433, B2=148052100) :banana:

Took 48 attempts, with expected 3.7% probability. A bit worse than expected, but not my usual dry streak :p

Yeah! Then, our next ">=2000 unfactored" ranges is 117.3M with 2001, 117.5M with 2002, 117.6M with 2012. And these ranges will definitely be completed "by itself" as the "wave-front" of GIMPS reaches there.
