COMMENTS
| Triangle A084938 * [1, 1, 1, 2, 6, 23, 105, 550,...] shifts left to
[1, 1, 2, 6, 23, 105, 550,...].
Eigentriangle A165490 = A084938 * its eigensequence, A165489 as a diagonalized
infinite lower triangular matrix.

FORMULA
| The sequence can be obtained by shifting down triangle A084938 one row, then
inserting a "1" as the first term, obtaining a new triangle Q. Then take the
Lim_{n->inf.} Q^n, obtaining a shifted left column vector = A165489 prefaced
with a 1. Delete the first 1, obtaining [1, 1, 2, 6, 23, 105, 550, 3236,...].
