OEIS Sequences

First occurrence of distances of equidistant lonely primes. Each equidistant prime is at the same distance (or has the same gap) from the preceding prime and the next prime. A54342

Primes P where the nearest prime is greater than 3·log(P) away. A330427

Balanced primes separated from the next lower and next higher prime neighbors by 42. A53077

Equidistant lonely primes. Each prime is the same distance (gap) from the preceding prime and the next prime. These distances are maximal: each distance is larger than all such previous distances. A58867

First pair of primes (p1, p2) that begin centuries of primes having the same prime configuration, ordered by increasing p2. Each configuration is allowed only once. A164987

Smallest prime p such that both p +/- 2n are primes closest to p, or zero if no such prime exists. A103709

a(0)=2. For n>=1, a(n) = a(n-1) + n if a(n-1) is composite; a(n) = a(n-1)*n if a(n-1) is prime. A131199

The first primes in centuries with three primes. A157131
