Joerg Arndt: the crossrefd sequence look rather uninteresting to me; similar to this one ...

Kevin Ryde: Where n falls in some ranges I suppose.  Umm +/-acos(log(2)) from a multiple of 2*pi for the 2s.  May want some sort of motivating problem.

Christoph B. Kassir: 2:17 This was what I thought, so I tried entering a slightly simpler sequence

09:58

Christoph B. Kassir: 4:38 This sounds familiar, I'll look into such problems

Christoph B. Kassir: Out of curiosity, are the cross-referred sequences of any particular interest?
