Base 43 can be added at the next update. All expected terminating sequences are terminated and all remaining composites are greater than C78.
Starting initial work on base 47.

OK, a lot of thanks ! I will test this program very quickly, but I can't get it to work at the moment, I don't know why yet ? Otherwise, more generally, in three days, I will be on vacation. I will try to do some data analysis. Hopefully the large amount of new data accumulated allows us to formulate new small conjectures ... that is our goal !

The source should compile on Windows, as well, but it's been so long since I've worked with Windows, that I wouldn't be able to even try. If there is some data in particular you'd like harvested, let me know and I can try to do that as well. I'm trying to keep a local uptodate set of all the tables, at the ready for such work. Have a Great Vacation!

Most of this vacation, I am going to work on the aliquot sequences. I have already started the preliminary work, I am writing and running programs.
But I would need a little help ! Would someone be able to calculate the following sequences, but only up to index 2, and of course, to enter the results on factordb : (9699690 * 23)^20 (9699690 * 23 * 29 * 31)^14 (9699690 * 23 * 29 * 31 * 37)^14 Indeed, my computer is very busy and that would allow me to have the results already next weekend. I still need more sequences, but the calculations will be shorter and I can handle them. @Edwin : I'm on a track... Since I looked again at your "2Stats.txt" file (from here), I got a new idea because of the fourth column. But I have to do some more analysis to be sure that it is worth it that I expose you on this forum what I noticed. The calculations I am requesting above relate to this work.

I have queued up index 1 for both of the first two, but they will take a little while to finish. Do you need index 2 also fully factored or just reach index 2? The bulk of my machines are running a rather large job right now, so I am somewhat limited.

I need just to reach index 2 but not to factor. Thank you very much Edwin !
