this vaguely reminds me of some stuff i used to think about
in connection with "riffs and rotes", but not sure this is
the place for an extended discussion.

feel free to register and start a thread at the inquiry site
that i use for such explorations.

Max, you said:

I've just found a page
where a number of sequences related to enumeration of classes of
chemical molecules are derived and references to the EIS book are
But one of the sequences is described as

"This series does not appear in the book by N. J. A. Sloane and S.
Plouffe [ The Encyclopedia of Integer Sequences , (1995), Academic

I've checked a few first terms in OEIS, and it is still not there.
Could somebody with chemical background submit this sequence to OEIS
with an appropriate description (a reference to this page and a maple
code from there will be also useful)?

Also, it makes sense to find the other mentioned sequences (that are
present in OEIS) and give a reference to this page in OEIS entries.
