Taking
93^75: 125/110
200^64: 139/116

93^75 terminates with P104.

unconnected 2022-05-05 10:01

Taking 200^63 next
Upd: It is quickly terminates with P105.

Someone (Anonymous) has been terminating whatever I add. I just added a few more, but my rate of adding is definitely slower than the rate of termination. Should I move the 140 digit threshold up a notch or two?

My original intent was to provide some easier terminations for those with lesser machine capabilities. I'm happy we brought in some newer members, but I think it will be more difficult to continue at this level.

Perhaps you can reduce the sequences to 145 or 143 digits instead of 140.
That will be less computation time for you and more for the others, since they seem to be getting ahead of you.
I don't know what others think ?

[QUOTE=EdH;605342]Someone (Anonymous) has been terminating whatever I add.[/QUOTE]I've noticed this too.
[QUOTE=garambois]Perhaps you can reduce the sequences to 145 or 143 digits instead of 140. [/QUOTE]I agree with increasing threshold to 145 digits.


Taking 99^75 next.

Moving to a 145 digit threshold would be very simple from my point and would immediately give a fair number of new sequences to the first post. Perhaps I will do that this evening. Any smaller sequences that may still show up will still make the list.

[QUOTE=EdH;605356]. . . would immediately give a fair number of new sequences to the first post. . .[/QUOTE]Actually, since I've been working with these sizes, taking them to 140, there aren't any left. I'm working at 147 digits already. However, I will shift my work to coincide with the new threshold starting now.

garambois 2022-05-06 19:00

OK, I think that's a good decision.
We'll see how it goes.

For fun, I plan to add 1152 and 1250 bases to the listings, even though they aren't yet added to the project pages. This should supply some really trivial sequences and we may even get the bases fully initialized somewhat quickly so they can be added.

I have chosen these two bases because they are unreserved and are the next two doubled square bases. This means that all the sequences for the tables should terminate, unless we find another rare open-ended one.

I will hold all the terminations listed in this thread until such time as the tables can be added to the project. I'm hoping this won't be too labor intensive and will provide some easy sequences again, as well as helping out the project.

Depending on the success/failure of this trial, I may add in the next sets of double square bases later on.
