[seqfan] Counting multigraphs

[Charles Greathouse]

A sequence defined in terms of A007717 was recently submitted, and an
editor asked if it and A007717 could be extended.  A007717 itself is
marked as an easy sequence, but I must admit that I'm not sure how to
extend it.  If it is easy, would someone add a program and more terms
(ideally a 10,000-term b-file, but the standard three lines would do
as well)?  I assume this is one of the things that is "well-known to
those who well-know it".

On the other hand, if it's not easy the keyword, at least, should be
removed (and whatever can be added should be).
