There is also the possibility of initializing the bases 648, 722 and 800 which are doubles of the squares between 578 and 882 that we already have on our page at the moment. For these bases, all sequences end trivially. And these are certainly the bases that are most likely to give us sequence endings on cycles. Quote:
Let me know when base 53 is ready to be put on the page. I'm sorry, but I personally don't use aliqueit so I can't answer this question. I use my own program written with Olivier Huber and Paul Zimmermann. This program uses several factorization methods including at the end an ECM method and CADONFS. It is written in python and I change the parameters according to the type of sequences I calculate. Sequences of the form n^i for example do not behave like sequences of the form 2^5*3^3*5*7*n on which I also work (growth at each iteration of a factor at least equal to 3).

I just use a queuing system to call aliqueit with the y flag, which simply calls yafu on each term after some TF and rho. The system also handles the configuration, which I set to a digit limit of 100 for the nontrivial sequences and a cofactor digit limit of 120 for the trivial ones (both through aliqueit parameters).

There's also a Perl script by yoyo that works directly with the db, so it updates each term. There's a thread about it. There is an option for term length, but not for cofactor length. It relies on YAFU for all the factoring.

@bur: As a general rule, if the sequence gets below 10 digits or so, you may want to stop it, upload, and check FactorDB to see if it merged. (You'll have to check the console scrollback after the downdriver run, once things have slowed down a bit.) Most (almost all?) merges happen below 15 digits, so don't bother checking if it doesn't get that far down.

Just to mention, you can open a second terminal and have Aliqueit do an upload without disturbing your main process. just use "s <term#>" in your command line, with <term#> being 0 or the last current term in the db.

Aliqueit shows a "merges with earlier sequence" for each 53^n because the i1 term is always smaller than i0.
How should that be handled? Technically it does merge after all... And a question about the process, aliqueit doesn't accept b^n as input, so do I really need alq_123...789.elf files with more than 100 characters or is there a better way? Quote:

Page updated.
Many thanks to all for your help. Added base : 44. I have changed the display of the Cycles in the "Navigation" part, so that we can see the complete and incomplete cycles.

Ok thanks. 53^30 terminated so it definitely merges with some lower sequence and a few others went below 15 digits. But I'll continue finishing the sequences to 110 digits and then check for merges in one go. Might waste some computation time on select occasions, but is easier for me.
