 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 59th year, we have over 358,000 sequences, and we’ve crossed 10,300 citations (which often say “discovered thanks to the OEIS”). Other ways to Give

A010051 * 0^(n-k) = an infinite lower triangular matrix with A010051, the characteristic function of the primes (0, 1, 1, 0, 1, 0, 1,...) as the main diagonal and the rest zeros. EXAMPLE First few rows of the triangle = 0; 0, 1; 0, 0, 1; 0, -1, 0, 0; 0, 0, 0, 0, 1; 0, -1, -1, 0, 0, 0; 0, 0, 0, 0, 0, 0, 1; ... CROSSREFS Cf. A010051, A054525.
