%N A139372 Let the binary expansion of n be n = Sum_{k} 2^{r_k}, let e(n) be the 
               number of r_k's that are even, o(n) the number that are odd; sequence 
               lists n such that e(n) >= o(n).
%C A139372 e(n)+o(n) = A000120(n), the binary weight of n. For e(n) = o(n) see A039004.
