Following these two messages, I contacted Paul Zimmermann and Olivier Huber. They both gave their agreement for me to publish here our program which calculates the aliquot sequences. But I preferred to present this program in a new Thread, see here. So, it will be easier to find this program in the future for those who would need it. If, however, this program should be of interest to some of you ?

Base 211
I am currently working on getting all values of base 211 up to at least 100 digits in size up to i = 50.
Attached is a list of the latest i values and their statuses within the FDB. Thank you, Nescro

Base 74 can be added at the next update. There is still a bit of work to do but the cool table helps me track the progress better. No need to reserve anything in my name. Merges should be checked for these sequences too. I did a little work on base 62 also.

Many thanks Nescro and RichD.
I will do the next update most probably on Thursday July 8 and I will add also the bases 211 and 74. For base 62, I will wait to hear from you. For base 211, I can see in the attached file that we have two sequences that end on a perfect number, one of them on 8128 ! We had not yet encountered this situation in our project.

Base 450 should all be green at your next update. If no one lets me know they're already there, I'll start working on base 338, greening up the nongreen cells. . .

But anyway, on Thursday I'm going to update all the bases of the project. Because during the month of July, I will have a lot of periods without access to my computer. So don't be surprised if sometimes it takes me a long time to answer on the forum, sometimes more than 15 days... Quote:
The more green cells we have by August, the better. Because I'm going to do a big data analysis. Maybe a 141st conjecture will come out of it ! But maybe nothing will come out of it, we can't predict anything ! Nothing ever went as I had planned on this project...

What would be of more interest to the project, initializing a new base or extending the nontrivial sequences of base 53 (or any other base)?

Edit: I've already completed the trivial sequences for both to i=20 with a combination of FactorDB and its elves, Alpertron's ECM/SIQS calculator, and a little bit of local yafu on my laptop. Last fiddled with by Happy5214 on 20210705 at 13:02 Reason: Progress already made

It is therefore more interesting to initialize a new base, especially in view of the future work in August. There are also bases which have only trivial sequences and which will be very interesting in August : the doubles of squares. The smallest not yet initialized is 2*18^2=648. There are also 2*19^2=722 and 2*20^2=800.

I'm curious to see if anything special is going to happen, I'm not sure what, but we better check it out !
