:bounce wave:

A tremendous load of top-5000 and top-3000 primes by SRBase! Great work BOINC!

This leaves us with only 8 top-3000 primes to go to hit our 2021 goal! :smile:

If you see any 1k bases that are not sieved to n=1M, that would be the first priority.

Another area to sieve would be bases with 11 or 12 k's remaining at n=100K. You could sieve those for...
