OK, perfect.
Many thanks !

Scratch that, base 48 is not done. I misread my own notes in my recent confusion. Only the trivial sequences are done. I'm expediting the non-trivial sequences, and I hope to have them done by Thursday.

OK, now base 48 is ready. The non-trivial sequences have been done to 100 digits. That went more quickly than I was expecting.

 2021-07-07, 05:05 #1229 Happy5214     "Alexander" Nov 2008 The Alamo City 77610 Posts It appears someone already did base 14288 below i=18 up to around 100 digits without reserving it (unless I missed it) and posted the results yesterday to FactorDB. Whoever did that should have just reserved the base officially for initialization, since I was waiting to see if anyone else wanted it before I reserved it. I guess I'll finish what's left.
 2021-07-07, 14:25 #1230 bur     Aug 2020 79*6581e-4;3*2539e-3 23·53 Posts All trivial sequences of base 53 for i < 99 are terminated. Just 53^99 is stubborn, it has 3^2 * 5 factors and decreases very slowly. Now at i12 it's a c164 co-factor. It'll take about a week to factor and before the sequence terminates I guess some more will follow. All non-trivials are done to 110 digits at least. Since you said that yoyo (is that yoyo@home?) will pick up the non-trivials sooner or later I guess it makes more sense to begin base 2*18^2 instead of continuing with base 53?

Confusingly, it's actually yafu@home, but yoyo is the forum user who manages it. I think yafu@home and the actual yoyo@home are both under the Rechenkraft.net umbrella, so they're basically sister projects.

-------------

Edit: Base 14288 initialization is done. I got lucky with i=34 with a 26-digit smallest factor on the first term that knocked the sequence below 120 digits, but not so lucky for i=32 (which was not completed). Other than non-trivial terminations (at primes) of i=3, 7. and 9, there was nothing else interesting with this base. Base 19116 is next, and I'll try to get as many trivial sequences done as possible before the update.
