%N A381099 a(n) is the smallest prime number that contains Fibonacci(n) as a substring.
%C A381099 If Fibonacci(n) is itself prime (n in A001605), then a(n) = Fibonacci(n).
%F A381099 a(n) = A062584(A000045(n)).
%e A381099 For n = 6, since Fibonacci(6) = 8, the smallest prime that contains 8 as a substring is 83, so a(6) = 83.
