Emeric puts his finger on the main dificulty:
(b) (3n^2 - n - 2)/2 might be the characteristic
function for a second order recurrence which
counts all sorts of interesting objects.
(c) numbers n such that an + b is prime,
especially for some small (coprime!) (a,b),
might be of interest in certain numbertheoretic
contexts.
and so on -- not easy to decide -- one man's
fish is another man's poisson.
I am just writing a paper which contains
about a dozen sequences. Nearly half are
already in (and are referenced). The others
would be fairly meaningless out of context,
but in context ... I shall send the paper to
Sloane's Dream Team, and if it grabs anyone,
I expect that they will submit the sequences
for me. Thanks in advance. R.
