Very curious! My OEIS bookmark just gave what I
said, although other sequences seemed to be
appearing in full. Your present suggestion
yields a variety of results:
1. A seemingly complete entry.
2. An entry in the form %I %S %T ...
3. Sequences from Stanley's Enumerative Combinatorics
4. An Index to OEIS
5. A007598 as a graph
6. Same as 1.
7. A000045 - OEIS Search Results (actually just
a search page, into which I typed A007598 and got
the bare sequence as originally described, together
with
At this point I got a phone call from Neil, who
very patiently got me registered, and I can now
see sequences and (almost, but not quite) edit
them. I need local help with updating my
Firefox, or something.
Thanks for various sympathies and help. At
least I don't feel quite as lonely as I did. R.
