FORMULA
Take antidiagonals of an array generated by taking binomial transforms of (1; 2, 3; 3, 4, 5; 4, 5, 6, 7; ...)
EXAMPLE
First few rows of the array are:
1, 1, 1, 1, ...
2, 5, 8, 11, ...
3, 7, 16, 30, ...
4, 9, 20, 44, ...
...
First few rows of the triangle are:
1;
2, 1;
3, 5, 1;
4, 7, 8, 1;
5, 9, 16, 11, 1;
6, 11, 20, 30, 14, 1;
7, 13, 24, 44, 49, 17, 1;
...
Example: The diagonal 3, 7, 16, 30, 49, ... (third row of the array) = binomial transform of (3, 4, 5, 0, 0, 0, ...).
