This question is related to this one.
Let $F_n$ be the $n$-th fibonacci number and $p(n)$ be the smallest prime factor of $$f(n):=F_{F_n}+F_n+1$$
The values $p(n)$ except for $n=11$ and $n=38$ upto $n=44$ are :
1 3
2 3
3 2
4 2
5 11
6 2
7 13
8 2
9 2
10 3
12 137
13 233
14 5

44 2
For $n=11$ , we get a prime number : $$p(11)=f(11)=1779979416004714279$$
What is the smallest prime factor of $f(38)$ , the remaining case. According to my search , there is no prime factor below $6\cdot 10^9$ , a doublecheck is welcome!
$f(38)$ has $8\ 168\ 944$ digits , so it is almost surely composite. To prove it , we need a prime factor , or a very long test. But I prefer a prime factor.
