FORMULA
| Triangle read by rows, T(n,k) = sum {j=k..n} A000292(j) = A000012 * (A000292 * 0^(n-k)) * A000012, 1<=k<=n

EXAMPLE
| First few rows of the triangle =
1;
5, 4;
15, 14, 10;
35, 34, 30, 20;
70, 69, 65, 55, 35;
126, 125, 121, 111, 91, 56;
210, 209l 205, 195, 175, 140, 84;
...
T(5,3) = 65 = (10 + 20 + 35), where A000292 = (1, 4, 10, 20, 35,...)
