@ yoyo :
Thanks a lot !
Just out of curiosity, are the calculations done by BOINC's yafu project ?


@ EdH :
OK.
So I'm going to focus using my tables on the case of the odd numbers you mention in post #364.

I don't remember being so hesitant in my work on aliquot sequences. I've been running my analysis algorithms for over a week now. Then finally, I decided several times to modify them to make the results more accessible or to make other phenomena appear.
And I observe a lot of conjectures. I observe so many that it is difficult to see which ones are the most interesting. I don't even know how to present all this to you clearly. I am preparing a huge post with a selection of some of the most representative conjectures.
But I still need more time.
My dream is to find a general conjecture, which was my original goal.
For example, I dream of being able to relate occurrences of prime numbers for bases p and q (prime p and q) to occurrences of prime numbers for the base p*q.

Yes they are handled by BOINC's yafu project.

I'm thinking if you can keep the first few terms locally then add the sequence to FDB once it drops below 200 digits. That requires a few extra steps but you could continue your analysis a bit further.

I just reread post #379 : OK, a is not an even number !
I misunderstood !
I'm sorry !
The conjecture seems to be true but a must be prime.
But I don't know how to prove it !

OK, thank you.
For the next update, very soon, I'll reserve the orange cells of base 3 for you.
Is that right ?
For the name of the contributor, I put "YOY" ?

You can remove my name from the colored cells (orange/green) in the n=30 table. I am done with them, so please release.

I do not deserve any credit for any of the green n=21 sequences, as I did no work on those. I don't know if you (Jean-Luc) did them or if they were done directly on FactorDB, but those shouldn't be attributed to me.
