COMMENT
|
T(n,n) = A000009(n), right side of the triangle;
T(n,k)=0 for n>0 and k<A002024(n); T(prime(n),n) = A067953(n) for n>0.

FORMULA
|
T(n, k)=b(0, n, k), where b(m, n, k)=1+sum(b(i, j, k): m<i<j<k and i+j=n).
T(n, k) = coefficient of x^n in Product_{i=1..k} (1+x^i). - Vladeta Jovovic (vladeta(AT)eunet.rs), Aug 07 2003
