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 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...

Perhaps a 6900 XT would also be good if the double precision performance is adequate.

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...
