%N A095741 Number of base-2 palindromic primes (A016041) in range ]2^2n,2^(2n+1)].
%C A095741 Note that there are no such primes in any range ]2^(2n-1),2^2n], as all 
               even-length binary palindromes are divisible by three (cf. A048702).
%C A095741 Ratio a(n)/A036378(2n) converges as follows: 1, 0.4, 0.230769, 0.069767,
