• Primes that remain prime through 4 iterations of the function f(x) = 9x + 8.at n=16A023326
• a(n) = p is the smallest prime such that p = n + h(n)^2 and p is the first prime following h(n)^2. The smallest immediate post-square primes with distance n = p - h(n)^2.at n=10A058056
• Smallest prime p such that p == 1 (mod prime(n)) and not p == 1 (mod k) for 2 < k < prime(n).at n=33A116605
