Perhaps I should say fully factored...to the optimal 91 bit depth! :smile: A factor would at least avoid the arduous P-1 and PRP tests, but those will also be an interesting challenge.
I was lucky...

I went ahead and took the liberty of reserving that exponent to 91 bits. It's a comparatively slow 100 days on my GTX 1080, but it will be good to have an exponent fully factored. I will check my...

Thanks Ken for the feedback in the last two posts. It will be interesting to see if Team Red can match the new Nvidia RTX A6000 (https://www.nvidia.com/en-us/design-visualization/quadro/rtx-a6000/)...

Thanks kriesel for the insight in the last two posts. I am interested to see if we can get a P-1 or PRP test going on an exponent once we get one TFed to 91 bits. Perhaps I could be tempted to get a...

Thanks all for the responses.
Interestingly, according to the following link, factoring to 91 bits would require over 150K GHz-days of computation, while a LL test requires only 91K:

Factoring to 87 bits
I've been thinking that in order to revive this project a bit, it might be good to get candidates up to 87 bits, as there are currently six that are at 86 bits and according to mersenne.ca (link...

Oddities in large P-1 candidates
Out of curiosity and audacity, I decided to look at the largest candidates (https://www.mersenne.org/report_exponent/?exp_lo=595799933&exp_hi=595800000&full=1) within Prime95's spectrum (<595.8M)....

You would have to ask Luigi to be sure, but my assumption would be that it was taken down due to the fact that Factor5 is outpaced by GPU programs like mfaktc by orders of magnitude and would thus...
