%N Triangle of coefficients, read by row polynomials P_n(y), that satisfy the g.f.: A038497(x,y) = Product_{n>=1} 1/(1-x^n)^[P_n(y)/n], with P_n(0)=0 for n>=1 and P_0(0)=1.
%C A038497 is the matrix square of partition triangle A008284. The first column forms the Moebius transform of {n*A000041(n), n>=1}. The inverse Moebius transform of each column forms the columns of triangle {n/k*A096798(n,k)}.
%e 1/A038497(x,y) =
