%N A113504 a(0) = 1. For n >= 1, a(n) = number of earlier terms of the sequence 
               that have the same number of ones in their binary representations 
               as n.
%C A113504 A115211(n) = A00120(a(n)) = number of ones in binary representation of 
               a(n) for n>0; record values: A115212(n) = a(A115213(n)). - Reinhard

%e A113504 The first 8 terms (terms 0 through 7) written in binary are [1,1,10,0,
               11,1,1,0]. Term 8 gives the number of earlier terms with the same 
               number of 1's in their binary representation as 8 (which is 1000 
               in binary, for one 1). a(8) = 5 because there are five terms among 
               the earlier terms with one binary 1 (terms with one 1: 1, 1, 2, 1 
               and 1).
