I plan to run one term for each of these:
Code:
347^63: 158/139 331^63: 156/143 1184^54: 162/144 313^63: 149/148 200560490130^14: 160/149 23^123: 157/150 307^63: 151/151

Me too. I realized that my posting there was in error the next day.Cool! By the end of today, 359^63 will also be a lone survivor of its base after I clear 359^65. At 156/154/131/t40, it's a bigger cofactor but the smallest factor size is nice.

359^65 terminates
Only 1 remains on base 359. A lot of remaining exponent 63's on the prime bases in the 300s.

I noticed a while back that we often had several bases with the same exponent left. I thought about seeing if there may be a reason that was easily determined, but didn't pursue the study.

313^63 terminates
Base 313 is complete! I'm still working on 347^63. It didn't move after you split the C139. The next index has a fully ECM'd C136. But I'll stick with it unless it hits a C>=140. I'm done with the 3 others that you split. Last fiddled with by gd_barnes on 20221006 at 13:56

I'll soon be tied up for the rest of the day. I'll evaluate where things are this evening and adjust then. At least we had one success.

347^63 is now at 151/148/13 fullECM. Releasing it. Many of these exponent 63s in the 300s are tough.
6 out of 7 of these sequences had the factor 3 when you picked them up. The exception was 347^63. Fortunately 313^63 dropped it quickly making it fairly easy to terminate. Status: 347^63: 151/148/13/full released 331^63: 155/148/3/t40 released 1184^54: 157/137/3/t40 released 313^63: terminated 200560490130^14: 159/148/3/t40 released 23^123: 156/139/3/none now beginning work 307^63: 150/131/3/none now beginning work What's up with exponent 63 in the 300s prime bases? I wonder if they often or always have a factor 3. There's also quite a few others in the 300s with 63 but have more than one exponent remaining. Now there's all of the C148s! Ugh!

I'll come back to these after I finish the c147s in the index 1 thread. I'll update tomorrow.

Sequences remaining by exponent for the 10 prime bases in the 300s:
61: 1 63: 7 65: 3 63 had 8/10 remaining prior to today. Weird!

I'll insert:
Code:
