 OFFSET 1,5 COMMENTS The triangular array (g(n,k)) in A274196 is defined as follows: g(n,k) = 1 for n >= 0; g(n,k) = 0 if k > n; g(n,k) = g(n-1,k-1) + g(n-1,4) for n > 0, k > 1. LINKS Table of n, a(n) for n=1..55. MATHEMATICA g[n_, 0] = g[n, 0] = 1; g[n_, k_] := g[n, k] = If[k > n, 0, g[n - 1, k - 1] + g[n - 1, 4 k]]; z = 300; w = Reverse[Table[g[z, k], {k, 0, z}]]; Take[w, z/3] CROSSREFS Cf.
