%C a(n) is the "level" of semiprimes.
%C The decomposition of semiprimes into weight * level + gap is A001358(n) = A130533(n) * a(n) + A065516(n) if a(n) > 0.
%C A184728(n) = A001358(n) - A065516(n) if A001358(n) - A065516(n) > A065516(n), 0 otherwise.

%e For n = 1 we have A130533(1) = 0, hence a(1) = 0.
%e For n = 3 we have A184728(3)/A130533(3)= 8 / 2 = 4; hence a(3) = 4.
%e For n = 20 we have A184728(20)/A130533(20)= 56 / 2 = 28; hence a(20) = 28.
