OEIS Sequences

Smallest prime p such that there is a gap of 2n between p and previous prime. A1632

a(n) is the smallest prime q such that, for the previous prime p and the following prime r, the fraction (r-q)/(q-p) has denominator n in lowest terms. A179234

Primes at the end of the first-occurrence gaps in A014320. A335367

First of four consecutive primes p,q,r,s such that (2·p+q)/5 and (r+2·s)/5 are prime. A358149

a(n) = 2·p + 2·n - 1, where p is the least prime such that next_prime(2·p) - 2·p = 2·n - 1. A59847

Primes of the form p² + q⁸ where p and q are primes. A122710

a(n) is the smallest prime(i) such that (prime(i) - prime(j))/(i - j) = prime(n) with i > j. A234511

a(1) = 2; thereafter, a(n) is the smallest prime not yet used which is compatible with the condition that a(n) is a non-quadratic residue modulo a(k) for the next n indices k = n + 1, n + 2, ..., 2n. A249797
