The sequence appears to be the set of natural numbers excluding
{1, 4, 7, 11, 14, 17, 20, 24, 27, 30, 33, 37, 40, 43, 46, 50, ...}
with adjacent member differences
3, 3, 4, 3, 3, 3, 4, 3, 3, 3, 4, 3, 3, 3, 4, ...
So I suppose that if one were interested in functions that generate
such patterns then there may be some merit in its inclusion.

)/(2*Pi*ln(2))
anyway, if I see
(..(exp(-ln(2)+...)/ln(2)))*ln(2)+...
then I already have some prejudice...
"argument(...)/2pi" does not improve anything ...
IMO that's complete nonsense, but of course I might be wrong...
Whatsoever, I think it is insulting to "submit" such a thing and let
tens or hundreds of people try their best in making a sense of it.
