%N Triangle of coefficients of certain polynomials used for G.f.s of columns of triangle A060058.
%C The row polynomials p(n,x) (rising powers of x) appear as numerators of the column g.f.s of triangle A060058.
%C First column (m=0) gives A000364 (Euler numbers). See A091742, A091743, A091744 for columns m=1..3.
%C The main diagonal gives A001818. The row sums give A052502. The alternating row sums give A091745.
%H W. Lang, <a href="/A060063/a060063.txt">First 8 rows</a>.
%F The row polynomials p(n, x) := Sum_{m=0..n} a(n, m)*x^m satisfy the differential equation: p(n, x) = x*((1-x)^2)*(d^2/dx^2)p(n-1, x) + (1+6*(n-1)*x+(5-6*n)*x^2)*(d/dx)p(n-1, x) + (3*n-2)*(1+(3*n-2)*x)*p(n-1, x), n >= 1, with input p(0, x)=1. - _Wolfdieter Lang_, Feb 13 2004
