- Fibonacci quotients: Fibonacci(p - Legendre(p|5))/p where p runs through the primes.at n=12A092330
- Numbers of the form Fibonacci(p-1)/p, where p are primes ending in 1 or 9 (i.e., A045468).at n=4A094808
- Let p = prime(n). Then a(n) = Fibonacci(p+1)/p if this is an integer, otherwise a(n) = Fibonacci(p-1)/p if this is an integer, and fall back to a(n)=0 if both are non-integer.at n=12A176951
- Number of ways to place 3 points on a triangular grid of side n so that no two of them are adjacent.at n=20A239569
