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.

Both of the two exponents above are listed at only 80 bits here: https://www.mersenne.ca/exponent/3321930461 https://www.mersenne.ca/exponent/3321930613

Taking 3321928373 from 83 bits to 84 bits.
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/bulkfactors.php Last fiddled with by ET_ on 20190606 at 13:09 Reason: timing error...
