EXAMPLE
| First few columns of A073133 are: (1, 1, 1,...); (1, 2, 3,...); (2, 5, 10, 17,...); (3, 12, 33, 72,...). As sequences, these are f(x), Fibonacci polynomials: (1); (x); (x^2 + 1); (x^3 + 2x); (x^4 + 3x^2 + 1); (x^5 + 4x^3 + 3x);...For example, f(x), x = 1,2,3...using (x^4 + 3x^2 + 1) generates Column 5 of A073133: (5, 29, 109, 305...).
Inverse binomial transforms of the foregoing columns generates the triangle rows:
1;
1, 1;
2, 3, 2;
3, 9, 12, 6;
5, 24, 56, 60, 24;
8, 62, 228, 414, 360, 120;
