 OFFSET 0,2 COMMENTS This sequence equals the reversal of row 2 of A167015 (when infinitely extended to the left), and then shifted left 1 place. 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'. The definition of A167015 may be relaxed to allow the triangle to extend indefinitely also to the left, making each row infinite. LINKS CROSSREFS Cf. A167015, rows: A167016, A167143, A167144, A167145.
