%N Numbers in A055039 but not in A044075.

%C Numbers whose base 4 representation ends in 3,2 followed by some number of zeros and includes at least one other 3,2. This means that, in spite of the initial terms, asymptotically most members of A055039 are not in A044075. In fact, A055039 has density 1/12, while A044075 has density zero. - _Franklin T.
