FORMULA

Lim_{n->inf.} (A171608)^n, a left-shifted vector considered as a sequence.

EXAMPLE

First few rows of triangle A171608 =

1;

2, 0;

0, 2, 0;

0, 3, 0, 0;

0, 0, 3, 0, 0;

0, 0, 4, 0, 0, 0;

0, 0, 0, 4, 0, 0, 0;

0, 0, 0, 5, 0, 0, 0, 0;

...

Let the triangle = M, then A171609 = Lim_{n->inf.} M^n
