 2020-11-22, 16:18 #78 Ensigm   Aug 2020 2·3·19 Posts 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)
 2020-11-24, 13:38 #79 Ensigm   Aug 2020 11410 Posts Now intending to work on the exponents in the second half of 56 M that has B1=B2≤700,000 and without a DC. As most of the exponents will be in Cat 3 and higher, I will reserve every exponent as TF before I start my work. If you see an exponent that is not currently reserved in the Primenet system, then it simply means I am not working on it. Declaration here is more for the recording of progress. Currently colloquially "reserved": - the first half 56 M (B1=B2≤690,000) Currently intending to do (will Primenet-reserve every exponent before I actually start working on it, so you don't have to avoid anything——there is no risk of me poaching your factor): - the second half 56 M (B1=B2≤700,000)
 2020-12-05, 04:54 #80 Ensigm   Aug 2020 2·3·19 Posts Report for the second half of 56 M (B1=B2≤700,000): 2 factors found out of 35 attemps (5.71%). Expected prob. 3.93%~3.94%. Now intending to work on the exponents in the first half of 57 M that has B1=B2≤700,000 and without a DC. I will reserve every exponent as TF before I start my work on it, so you don't have to avoid them. Currently informally "reserved": - the first half 56 M (B1=B2≤690,000) Currently planning to do (will Primenet-reserve every exponent): - the first half 57 M (B1=B2≤700,000) Last fiddled with by Ensigm on 2020-12-05 at 05:03 Reason: typo: min prob is 3.93
