• Quadruple Hex-primes: let f(n) = A102489(n); then sequence lists primes p such that f(p), f(f(p)). f(f(f(p))) and f(f(f(f(p)))) are also primes.at n=31A237440
• Odd k for which abs(2^m - k) is nonprime for all m < k.at n=28A263865
• Number of permutations of [n] whose cycle lengths avoid primes.at n=9A329944
• Prime numbersat n=10262
