I did the correction in mentioned post, re gender (his->its) in four places. FWIW the things work the same in Romanian, we have a neutral gender, but we don't have an "it" for it. Neuter things are...

Yafu siqs on 93 digit semiprime (p47*p47) on 10 cores, 10 threads, ~84k relations needed, 166 seconds.

NFS on the same number is about 30 40 seconds slower.

Yafu siqs is very fast / fine tuned. Except for very old versions and CPU, the cutoffs were always around 100 digits, a bit over. I also get 103..106 depending on what else the computer does.

I'm done (for now) with 6^9. I added a few thousand terms to it, and it gave me "false hopes" and palpitations every time it went low, but right now it got the "devil's driver" (for the 6th time!)...

I am recently arguing with 6^9, to which I put few hundred terms or so. It has no driver, and it is up-down-ing, hitting its head on the "resistance line" for a while now. :smile:

Welcome to the fray.

Jean Luc may add 385 to the page linked in the first post of this thread. It should be the easiest way. Then anybody can follow your progress if he/she wants, and eventually...

You always store the first. In fact, there are no merges "so high", all merges happen at very low digit count. The reason to store higher lists (people use to keep 80 and 100) is that the search is...

I have my own 10, 12, 15, 20, 30, 50, 80 digits lists. That is the first x digits number that some sequence reach, for which I store the "smallest starter" and the "longest sequence". They are huge...

Thanks a billion. That is exactly what we expected. We use ctrl+click a lot. Our mouse has a "ctrl" button too (side button, whose function can be set, to press with the thumb). Now, if we don't ask...

Hey Jean-Luc, Maybe you can add base 28 too... I added few factorization to the DB for 28^n.
