%N A060074 Triangle A060058 by diagonals.
%C A060074 Row sums give A060059. Columns give A000364 (Euler numbers), A000364, 
               A060075-78 for m=0,..,5.
%C A060074 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).
