COMMENTS

The nth prime p is in this sequence iff A001602(n)=p(5/p) (that is the maximum possible value of A001602(n)).
Union of A000057, A106535 and {5}.


LINKS

Table of n, a(n) for n=1..61.


EXAMPLE

7 belongs to this sequence since (7/5)=1, F(8)=21 and 7 does not divide F(1) to F(7)


PROG

(PARI) forprime (p=2, 500, wss=pkronecker(5, p); for(n=1, wss, if( fibonacci(n)%p==0, if( n==wss, print1(p", "), break) ) ))
