What is a divisibility sequence? Just glancing at examples doesn't
tell me.
There is no definition for divisibility sequence in either Mathworld or
Wikipedia. (Wikipedia does have an entry for Elliptic Divisibility
Sequence.) Does this term (without the elliptic) occur in the
mathematical literature anywhere? (A087612 has a reference to a paper
it claims is titled "Primes in Divisibility Sequences"; but tracking
down the link, I find it is actually titled "Primes in Elliptic
Divisibility Sequences".)
I can't support adding a new keyword for this concept without more
widespread recognition in the mathematical community than appears to
exist.
I would suggest the following:
(1) Write a short description of what a divisibility sequence is, and
the properties entailed thereby, and put it somewhere it can be
referenced. (One possibility is to send it to Neil and have him put it
the directory for the OEIS.)
(2) Perform your suggested survey of the OEIS, putting in appropriate
comments, and links to the document described in (1). Possibly also
add an entry to the OEIS index, and reference the sequences you find.
(3) Write up a paper describing the concept, proving the associated
properties and listing divisibility sequences in the OEIS, and get it
published.
(4) By this point, the OEIS will probably have gone Wiki, and the
introduction of a new keyword will be a somewhat different issue than
it is now. That would be the time suggest a new keyword, in any event.
If this concept has been described in the literature, step 1 can be
modified to finding or creating an on-line reference if possible, with
a link to it being added in step 2; step 3 can then be skipped. A
print reference would also be useful.
