25 days for a 2080Ti.
Maybe 15 if you get a 3090???

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 local electronics store for a 3060 Ti tomorrow morning, which should give a faster ETA at an affordable price.

Perhaps ... but I still hope you find a factor.

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

I was lucky enough to get a 3060 Ti this morning, despite there being over 100 people in a line that started forming the day before! I will install that and see what the new ETA is.
