%N INVERTi transform of A054765: (1, 3, 19, 160, 1744, ...).
%C This sequence convolved with A054765 prefaced with a 1: (1, 1, 3, 19, 160, ...) = (1, 3, 19, 160, ...), equivalent to row sums of triangle A155729 = A054765.
%F INVERTi transform of A054765 starting with offset 1: (1, 3, 19, 160, 1774, 23184, ...).
%e We write (1, 3, 19, 160, ...) in reverse: (..., 19, 3, 1), top row.
%e Bottom row = (1, 2, ...), so that the format for a(3) = 14 becomes: ...3, 1 = A054765: (1, 3, 19, 160, ...). ..., 1, 2 for current format, take dot product = (3*1 + 1*2) = 5, then subtract from next term in A054765, getting (19 - 5) = 14. So a(3) = 14.
%e Continuing with analogous operations, we get (1, 2, 14, 121, 1383, ...).
%Y Cf. A054765, A155729.
