I am not actively working on this sequence now. Would consider running GNFS if there's an effort to find a good poly / params.

I can confirm I have tested the whole 6M..8M range, based on the sieved input file I was given.

The first untested candidate is now: (10^10954843-1)/9 so the search limit is actually about 10.9M.

My vaccine doses 1 and 2 were Moderna, then I decided to mix-and-match with a Pfizer booster in September.

None of the three produced any noticeable side effects for me other than a sore arm.

I've tested "-g 72", "-g 144", "-g 600" and for fun, "-g 6192". All produce about 7.5M to 8M p/sec.

With "-G 2" or "-G 4" added in as well, i can get up to about 9.5 to 9.8M p/sec, but no higher.
