%N a(n) is the smallest prime number that contains Fibonacci(n) as a substring.

%C If Fibonacci(n) is itself prime (n in A001605), then a(n) = Fibonacci(n).

%F a(n) = A062584(A000045(n)).

%e For n = 6, since Fibonacci(6) = 8, the smallest prime that contains 8 as a substring is 83, so a(6) = 83.

%Y Cf. A000040, A000045, A001605, A062584.
