%N a(n) is the number k, 2^n < k < 2^(n+1), such that k/c(k) is a minimum in the interval, where c(k) is Hofstadter-Conway sequence A004001.

%C The ratio of k/c(k) (where c(k)=A004001) reaches a maximum of 2.0 when n is a power of 2. When n=6 the ratio has a relative minimum of 1.5, so a(2) = 6.

%Y Cf. A004001.
