%N Limiting reverse row of the array A274196.

%C 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.

%t g[n_, 0] = g[n, 0] = 1;

%t g[n_, k_] := g[n, k] = If[k > n, 0, g[n - 1, k - 1] + g[n - 1, 4 k]];

%t z = 300; w = Reverse[Table[g[z, k], {k, 0, z}]];

%t Take[w, z/3]

%Y Cf. A274196, A274199, A274200.
