COMMENTS

a(n) is the "level" of squares (A000290).

The decomposition of squares into weight * level + gap is A000217(n) = A133150(n) * a(n) + A005408(n) if a(n) > 0.

A184220(n) = A000290(n) - A005408(n) if A000217(n) - A005408(n) > A005408(n), 0 otherwise.

EXAMPLE

For n = 3 we have A133150(3) = 0, hence a(3) = 0.

For n = 5 we have A184220(5)/A133150(5) = 14 / 14 = 1, hence a(5) = 1.

For n = 25 we have A184220(25)/A133150(25) = 574 / 82 = 5, hence a(25) = 7.
