Base 94 has all sequences ending or > 123 digits. I plan to ECM the larger candidates, but will move on to base 127 for now.

Initializing base 86.

Page updated.
Many thanks to all for your help.

[B]Added bases : 90 and 94.[/B]

@kruoli :
Since you still want to do some work on Base 94, I have noted it as reserved by you for the time being.

 EdH 2022-03-07 15:51

I am going to be doing some playing with base 85. I don't need it reserved for me. At least not yet, so if someone wants it, take it, and I'll stop my "playing."

As for the current status:[code]
85^2:i22 merges with 1134:i9
85^3:i5 merges with 1074:i2

exponents 1, 4-9, 11, 13, 15, 17, 19, 21, 23, 25, 27 and 31 are all terminated[/code]

Sometimes the question pops up on which sequence yafu@home is currently working and which an have been already dropped.
and if you want to check it somehow automatically, it can be done based on

yoyo

Thank you very much yoyo for these links.
They will be very useful to me !
I'm going to have to do a very big cleanup on the project page and remove lots of yoyo reservations.
[U]Just to make sure I understand :[/U]
Can you confirm me for example that for the base 3, there is only the sequence 3^132 which is still reserved by yoyo ?
Do you also confirm that no other sequence of base 3 will be calculated in the future ?
The dropouts are definitive, aren't they ?

 yoyo 2022-03-08 19:28

Yes you are right, 3^132 is the only one for base 3 which I still run. The others droped out because the remaining composite was to large or the sequence finished.

OK, thank you very much for these explanations.
So I will change the reservations for the bases initially reserved entirely by yoyo, but this will certainly take some time.
If someone calculates a sequence of the base 3 that is no longer reserved by yoyo and so the remaining composite becomes smaller again, yoyo will not automatically resume the calculations, is that right ?
The abandonment is definitive ?

 yoyo 2022-03-09 19:38

Yes, the abandonment is definitive.
I would have to add the sequence manually to continue it.

 garambois 2022-03-09 19:57

OK, thank you very much.
Now everything is very clear in my mind.
I preferred to make sure of all this to absolutely avoid yafu and some of us making the same calculations.
We must not waste our resources !

The work done by yafu is really colossal.
It is a very powerful tool.

:tu:

Thank you very much yoyo for pushing the calculations so far for all these sequences !!!
