90 digit, it is a matter of time before we despair or rejoice.

mshelikoff 2016-12-19 04:29

Is there an archive of the name changes to this thread and when they took place?

Batalov 2016-12-19 04:34

Yes, there is.

mshelikoff 2016-12-19 04:45

Oooo...how is it visible? Can mere mortals see it? Who changes the name? Am I asking too many questions? There should be a huge graph of the sequence with a label every time there was a change in the name of the thread and the new name each time. It would be a little like Minard's map of Napoleon's 1812 Russian campaign.

I see some 2^2 * 7 ahead. :bangheadonwall:

Well, I guess that's it for another 2000 iterations.

Sigh. What do we need to get rid of the 2^2*7?

[QUOTE=ryanp;449540]Sigh. What do we need to get rid of the 2^2*7?[/QUOTE]

[QUOTE="http://www.rechenkraft.net/aliquot/analysis.html"]For example, when the 2^2 · 7 driver takes the form 2^2 · 7^2, its class of -1 temporarily increases by 3 (the 2s count of 7) so a mutation will occur when the 2s count of t is 2 or 1.[/QUOTE]

a change in certain values to allow for a class change so a mutation can occur and get out of it potentially.

Batalov 2016-12-19 20:53

You do need a 2^2 * 7^2 (or 2^2 * 7^4 or other even degree) and one prime* ...or two primes of 4k+1 type.

The excitement (and the shortcoming!) of aliquot sequence riding is sort of like surfing: you need a good wave and then you have even less control than in surfing; you just ride the wave. It can be even more adequately compared to the joy of playing pinball.

* and that prime needs to be bla, bla, bla, you know: Many additional conditions.

The driver has been lost [URL="http://factordb.com/sequences.php?se=1&aq=4788&action=last20"]again[/URL].
This song will play forever. :)
