The elements of this series may appear as "the size of the Bona equivalance
classes among 132-avoiding permutations of length n," as defined in Doron
Zeilberger's paper 1403.5664 on the arXiv. If so, that would be a very
interesting datum toward the conjecture he proposes, and I would like to
know how this triangle might be related to the question.
Unfortunately, I don't understand the reference to the other sequence, and
there is no example section explaining how the numbers are calculated. Can
anyone illuminate the definition? I've dropped a line on Tilman's page and
I'm also asking here (where he may respond anyway). I'd very much like to
see if this connection holds.
