Terminated: 17^127: 92/66 (already done by another) 6^204: 98/89 done 54^92: 112/101 done 7^185: 125/124 (already done by another) 91^65: 127/120 done Taking: 10^148: 139/132 11^145: 139/121 12^134: 138/137 12^142: 136/117 12^146: 139/134

There must be an error : 17^123 is not terminated on FactorDB.

Currently, I am extending bases 76, 78, 94 and 127 (the ones I initialised). I am going to try to terminate all possible sequences up to 135 or maybe 140 digits. There are already progresses you may include in your update if you like. I will state in the main thread when I have finished my work.

A C99 is maybe a 10-minute job on a modern desktop CPU, less than an hour on many laptops. C107 maybe 3 times as hard. If you think these take a long time, I think your factoring software is not set up correctly, or you're not using the right tools.
If you're in windows, yafu can do these quite easily.
If you run linux, get CADO set up.

OK, I'll reserve these 4 bases for you (76, 78, 94 and 127).

Correct: I officially have no idea how to find yafu's post-nfs app.
Reference image attached.
Found it!
