%N a(1) = 1. a(n+1) = the largest positive integer that, when written in binary, occurs as a substring both in binary n and in binary A175302(n), where A175302(n) = Sum_{k=1..n} a(k).

%e The sum of the first 13 terms of this sequence is 22, which is 10110 in binary. 13 in binary is 1101. The largest integer that, when written in binary, occurs in both of these binary representations is 6, which is 110 in binary. So, a(14) = 6.
