%N Triangle of degree numbers for certain polynomials.
%C This is the array ay(N,m)= A104471(n+m-1,m) with numbers m>N omitted because they are identical with ay(N,N).
%C a(n,m)=sum(j*floor(n/j),j=1..m), n>=m and zero else (but actually one should repeat the a(n,n) numbers for n<m).
%H W. Lang: <a href="/A104472/a104472.txt">First 10 rows.</a>
%e ; [2,4]; [3,5,8]; [4,8,11,15]; [5,9,12,16,21]; ...
%Y Main diagonal a(n, n)= A024916(n), n>=1.
