%N Triangle of coefficients of polynomials used for g.f.s of columns of A067304.

%C The row polynomials p(n,y) := sum(a(n,m)y^m,m=0..n), n>=1, appear in the g.f.s for the n-th column of triangle A067304.

%F a(n, m)=[y^m](p(n, y)), n>=m>=1, a(0, 0)=1, else 0, where p(k, y) is, for k>=1, defined by the g.f. of the k-th column of triangle A067304(n, k).
