Everything is looking great from my perspective and I've added the new bases to the other thread, although for the near time I won't do any work above base 20 for the other thread.
Thanks for all the work. I hope we aren't giving you too much with the other thread. Edit: 24^110 is still being carried in the other thread and shouldn't be lost, so it shouldn't be an issue to let it stay there from my viewpoint. Last fiddled with by EdH on 20220626 at 21:53

Right now with the sameparity exponents, if a base has been initialized here but does not show on the web page or you have not had time to include it in your listings in the other thread, I'll report any termination here. If it is shown on the web page and in your listing, of course I'll report it there.

But I think once the mergers are removed, the quantity will decrease a lot, at least if you can do that ! Quote:

It's just that I can't always do the updates right away and sometimes it takes 10 or 15 days or even more depending on the period.

Here's a full list of all primes >10^9 that occur in two bases, with all merges reflected only once. This listing does not include the most current bases, but otherwise includes the entire set of tables. In the case where a prime was found in several merged sequences, only one of the merged sequences is listed. This list is for all multiples >10^9. Of note, I don't believe there are any triples and there are no examples larger than 12 digits. Here are the 12 digit primes:
Code:
109964639887,193,22,263 109964639887,40,19,182 126249927637,15472,5,113 126249927637,67,75,5 142754777149,101,32,504 142754777149,52,39,640 154198251007,17,76,702 154198251007,22,87,1336 194041181491,439,22,392 194041181491,76,35,2974 220689850709,12496,19,494 220689850709,15,12,3377 389689791443,10,109,4650 389689791443,15,34,1318 392293758937,10,85,807 392293758937,42,23,2984

Bases 239 & 241 can be added at the next update.

This time, everything seems to be perfect. I did several checks, everything is good. I will do some more analysis in 2 weeks. A priori, the occurrences of these primes seem to be completely random. I will have to be creative to try to find something else, I will look, even if I think that there should be nothing else than random. I will also try to find these lists with my own program, to confirm them. I remember that more than two years ago you sent us lists that you had obtained with other programs. And it was only a year later that I noticed something that led to a conjecture. So we will have to be patient !

I have terminated the following sameparity sequences:
239^53, 239^55, 239^57, 239^63, & 239^67 241^53, 241^55, 241^57, & 241^59

It's been a while, but I'm assuming the inclusion standard for a base is still initializing everything to 100 digits. If that's the case, base 306 (306:i1=396=276:i1, so this falls under the "merges into open" category) can be added. Its sameparity sequences are actually terminated up to 140 digits thanks to some lucky ECM hits.
After some personal Riesel assignments, I'll resume base 210 at 210^9 (210^5 and 210^7 have reached C120+ cofactors, so I'm done with those).
