%N Common factors of 2^p-1 and the p-th Fibonacci number, p prime.
%C The shown members of the sequence are all prime.
%F a(n)=gcd(2^A080050(n)-1, fibonacci(A080050(n))).
%e Example: A080050(1)=11 and 89 divides both 2^11-1=2047 and F(11)=89, so 89 is in the sequence.
%Y Cf. A074776, A079506, A080050.
