n=21 is now done to i=60, and I'll release the range from i=52 to 60. I'll take the same base to i=70, and I'd also like to reserve n=3 between i=20 to 40 (except i=28) to get them to 120-digit cofactors.

I'm quite late in my arrival to the playground, but I see the 6-table has lots of transparent spaces. Unless told to stop, I'll try to cause them to become orange. No personal need on my end to show a reservation. If I catch one appearing for someone else, I'll stop my work. All my calculations are done directly with the db, so it will show exactly where my machines are ATM.

Will the table catch up with my work by itself, or do I need to provide periodic info here?

OK, page updated.
Thank you all for your help !

@richs : Thank you very much.

@Happy5214 : Done. Thank you very much. Don't hesitate to let me know if I've done something wrong with your reservations !

@EdH : Welcome to our club and thank you very much ! I preferred to put base 6 on reservation for you, to prevent someone else from doing the same job as you. If you want me to remove these reservations, don't hesitate to ask me ! You do not need to give details of the progress of the calculations here. At the next update, the progress of the calculations will be taken into account automatically. Just enter your results on factorDB. Please also let me know if you don't like the acronym "EDH" to indicate your contribution, I can change it. The same applies if you prefer that I put your real name in the contributors table instead of your pseudonym "EdH".


My own progress :
The calculations for base 12 are complete. Calculations for base 14 are in progress. Non-trivial end for 14^49 on prime 59.

Thanks! EDH is fine for my code. Edwin Hall would probably be better for contributors. Once I catch that a sequence has reached 120 dd (orange) status, I will drop that one, at least for now.

Many thanks !

If you see that some of us extend the calculations a little bit beyond 120 digits, to 122 or 123 digits (or more !), it's because sometimes the elves change a cell from orange to white again.
But this is very unlikely if :
- The last term of the aliquot sequence has "only" 120 digits and if the sequence has a driver.
- The cofactor is ecmd and is at least 110 digits long.

Thanks! Depending on the scripts/software I'm using I probably won't catch all of them right at 120, as shown already for a couple. And, as I have been an elf from time to time, I've seen how sequences can move ahead via their work.

Personally, my strategy (for virtually all of my aliquot sequences) is to keep going with the sequence until the cofactor is at least 120 digits and it passes the "normal" level of ECM (4/13 in yafu), regardless of the overall size of the last term. That's what I'm doing advancing n=3.

As an aside, I've already finished my work on 3^20 and am releasing that one.

This is an even more robust strategy than mine.
It's an excellent strategy !
But it's an even more computing time-consuming strategy !

This is a good strategy to keep the elves away for now. For this project, I expect to work toward coloring the boringly transparent squares so all the tables can look "colorful."

But each should play as they desire, since this is all "for fun."

Note: I do bounce around to different projects. Not sure how long I'll play here, but for now. . .

That goes without saying. It's the basic principle !
The main thing is to enjoy yourself.

And besides, while having fun, if we calculate enough aliquot sequences to be able to notice something, if there is something to notice, we might be able to formulate a new conjecture, who knows ?
That is the goal and what we are working towards.

And in that case, we'll have even more fun !

And, this is what compelled me to try to fill the tables with bright colors. . .
