Sequences >10^6 open for reservations
 
I have a page of [URL="https://sites.google.com/site/mynumbersandfactors/aliquot-sequences-list-version"]sequences[/URL] on my site, and I was wondering if anyone wanted to extend them. I'm not working on 4198862272 anymore, so if anyone wants to give it a go, go ahead. I'll put your name under the "Reserved?" column. I'm currently working on sequence [URL="http://www.factordb.com/sequences.php?se=1&aq=2158184014&action=last20&fr=0&to=100"]Rya'c[sub]94[/sub][/URL], so I currently have a reservation on that one. NOTE: Some of these sequences have merged with sequences that are in [URL="https://www.rechenkraft.net/aliquot/AllSeq.html"]this list[/URL].

Is pdazzl still working on 8675309^2+1? It hasn't been updated in over a year, and I don't want to put "No" if it's still reserved.

Reserving 2158184014

I hope that works. You'll have to start allowing/tracking reservations >1M sooner or later.

I have 9 "very high" sequences which I occasionally work, when there is nothing else "more important" to allocate resources for, or when I need to test a new build for a short period of time. Therefore do not touch them. Namely:

8386560
10077696
288600576
4620994560
18486235136
15241578750190521
16666407004581734400
22783555310432716800
15241578775156479157107515989284229902225

(edit: these are of some minor theoretical interest and/or curiosities for me, like for example the two sequences from Garambois' list, or playing with a D11 and a D12 drivers, or some powers of 6, as described in the past)

I've been working on 22689424 off-and-on, usually when I have no queued sequences and my Internet connection has gone down. 52145214 merges into it at some point, so that's why I have that one. I consider it reserved.

Reserving 4198862272 again. It lost the guide (2[sup]3[/sup]*3*5 -> 2[sup]4[/sup] with 3).

I reserve all the aliquot sequences that start on the integer powers of 2, 3 and 5.

Why ?

At the moment, I am calculating the aliquot sequences that start on the integers n = 2 ^ i. I am at i = 432. But it begins to be long. All those aliquot sequences end with 1 for now.
I also calculate the sequences for the n = 3 ^ i (I am at i = 66) and n = 5 ^ i (I am at i = 62).
For the odd values of i, those sequences end at 1, but for the even values of i, I usually fall on OE sequences. Then, I then stop at 120 digits.
I reserve therefore all the aliquot sequences that start on the integer powers of 2, 3 and 5.

Later, I will try to calculate the aliquot sequences that start on the integer powers of 6, 7 and 10 (integer powers of 8 and 9 are included in integer powers of 2 and 3). But if someone wants to try before me and put the results on factordb... If someone does this work, please tell me here, so I can use the results.
