COMMENTS

a(n) is the "level" of triangular numbers.
The decomposition of triangular numbers into weight * level + gap is A000217(n) = A130703(n) * a(n) + (n + 1) if a(n) > 0.

EXAMPLE

For n = 3 we have A130703(3) = 0, hence a(3) = 0.
For n = 24 we have A184218(24)/A130703(24) = 275 / 55 = 5, hence a(24) = 5.
