%N Irregular triangle which contains in row n those partition numbers A000041(n*(2m+1) + m + 2) which are congruent to 0 mod (2m+1) for 1 <= m <= n.
%D Robert Kanigel, The Man Who Knew Infinity, Washington Square Press, New York, 1991, page 302.
%e The first line contains A000041(9)=30 from n=2 and m=1 and A000041(14)=135 from n=2 and m=2.
