%N Column 0 of the matrix cube of triangle A167015.
%C This sequence equals the reversal of row 3 of A167015 (when infinitely extended to the left), and then shifted left 1 place.
%C In triangle T=A167015, row n of T equals the initial n terms in column 0 of matrix power T^n, reversed and with an appended '1'.
%C The definition of A167015 may be relaxed to allow the triangle to extend indefinitely also to the left, making each row infinite.
%Y Cf. A167015, other rows: A167016, A167142, A167144, A167145.
