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

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

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.

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

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

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

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.
