OEIS Sequences

Record gaps between primes (upper end) (compare A002386, which gives lower ends of these gaps). A101

Number of set partitions of strict integer partitions of n that have distinct block-sums. A279375

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

Smallest base b > 1 such that both prime(n) and prime(n+1) are base-b Wieferich primes, i.e., p = prime(n) satisfies b^p-1 == 1 (mod p²) and q = prime(n+1) satisfies b^q-1 == 1 (mod q²). A259075

Upper prime of a record difference between it and the second prime before it. A31134

Primes that show the slow decrease in the larger values of the Andrica function Af(k) = sqrt(p(k+1)) - sqrt(p(k)), where p(k) denotes the k-th prime. A84975

Sequence of primes 2·p(k) + 3 such that 2·p(k) + 3, 2·p(k+1) + 3, 2·p(k+2) + 3 are consecutive primes, where p(i) denotes the i-th prime. Sequence terms are 2·p(k) + 3. A89450
