Previous ranges 54.5 M (B1=B2≤730,000) and the second half of 55 M (B1=B2≤690,000) should now be finished and I am "unreserving" them.
Report for range 54.4 M (B1=B2≤730,000): 0 factors found in 18 attempts (0%). Expected probability 3.81%~3.83%.
Report for range second half of 55 M (B1=B2≤690,000): 0 factors found in 12 attempts (0%). Expected probability 3.89%~3.92%.
Currently working on:
 the first half of 56 M (B1=B2≤690,000)
