Year-end appeal: Please make a donation to the OEIS Foundation to support ongoing development and maintenance of the OEIS. We are now in our 61st year, we have over 378,000 sequences, and we’ve reached 11,000 citations (which often say “discovered thanks to the OEIS”).

%N Column 0 of the matrix 5th power of triangle A167015.
%C This sequence equals the reversal of row 5 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, A167016, A167142, A167143, A167144.
