COMMENTS

a(n) is the "level" of even numbers.

The decomposition of even numbers into weight * level + gap is A005843(n) = A090369(n-1) * a(n) + 2 if a(n) > 0.

EXAMPLE

For n = 3 we have A005843(2)/A090369(2)= 4 / 4 = 1; hence a(3) = 1.

For n = 24 we have A005843(23)/A090369(23)= 46 / 23 = 2; hence a(24) = 2.
