%N A147762 a(n) is the smallest positive integer m with exactly n zeros and exactly 
               n ones in its binary representation and with n represented in binary 
               as a substring of the binary representation of m.

%e A147762 6 represented in binary is 110. 2103 represented in binary is 100000110111, 
               which contains exactly six 0's and exactly six 1's and contains 110 
               as a substring (100000{110}111). Since 2103 is the smallest positive 
               integer that satisfies the conditions, then a(6) = 2103.
