%N Triangle A060058 by diagonals.
%C Row sums give A060059. Columns give A000364 (Euler numbers), A000364, A060075-78 for m=0,..,5.
%C Triangle can be used to express the Euler numbers E(n)=A000364(n), n >= 2, in terms of the numbers A060080 (scaled sums of squares), according to E(n+2)= sum(a(n,m)*A060080(m+2),m=0..n).
%F a(n, m)= a(n-1, m-1)+(m+1)^2*a(n, m+1), a(n, -1) := 0, a(0, 0)=1, a(n, m)=0 if n<m.
%F a(n, m)=A060058(n, n-m).
