%N A113503 a(1) = 1. For n >= 2, a(n) = number of earlier terms of the sequence 
               that have the same number of ones in their binary representations 
               as n.

%e A113503 The first 7 terms written in binary are [1,1,0,10,0,0,0]. The 8th term 
               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) = 3 because there are three terms among the first 7 terms 
               with one binary 1 (terms with one 1: 1, 1 and 2).
