COMMENTS

Numbers k such that k divides Fibonacci(k) are listed in A023172.

All powers of 5 belong to A023172.

5^n divides Fibonacci(5^n).

a(n) == 1 (mod 1000).

{a(n+1)/a(n)} = {1, 3001, 158414167964045700001, 62351961552434956321060201440347372028390478647963811251289490034177804212636326088548682319305439375001, ...}.
