Hot dang, that'd be quite an achievement. On my RTX 2070 I estimate that would take 82 days (if it wasn't factored first )!

Updated the stats, looks good to have multiple simultaneous checkouts on the graph again.

Remember that James Heinrich maintains a database with very high exponents. I think he should be contacted when ranges are done.

I'll reserve 3321930461 and 3321930613 up to 85 bits.

Perhaps GIMPS should also be informed?

Both of the two exponents above are listed at only 80 bits here:

It will take just 30 minutes on an old Nvidia GT 710 to go from 8 to 72 bits 6 hours on my RTX 2060, on the go. I guess I should communicate the result on the "Report results thread" and paste the line to https://www.mersenne.ca/bulk-factors.php Last fiddled with by ET_ on 2019-06-06 at 13:09 Reason: timing error...

James Heinrich's site mersenne.ca is the place for TF for p>999999999. mersenne.org will refuse assignments or reports outside its range. See the attachment at

I took a couple of exponents as well, but did not add them here.
