Comments

a(n)/a(n-1) appears to converge to phi.

The sequence generated is first (1, 1, 1, 2, 4, 6, 10,...), but by convention we drop the first "1".

Equals row sums of triangle A144024.

Example

The operations in steps generate(1, 1, 1, 2...).
a(4) = 4 = (1, 1, 0, 1) dot (1, 1, 1, 2) = (1 + 1 + 0 + 2).
