OEIS Sequences

Safe primes p: (p-1)/2 is also prime. A5385

Primes (lower end) with record gaps to the next consecutive prime: primes p(k) where p(k+1) - p(k) exceeds p(j+1) - p(j) for all j < k. A2386

a(0)=2; for n>=1, a(n) = smallest prime p such that there is a gap of exactly 2n between p and next prime, or -1 if no such prime exists. A230

Euclid-Mullin sequence: a(1) = 2, a(n+1) is smallest prime factor of 1 + ∏_k=1..n a(k). A945

Primes of the form 8n+7, that is, primes congruent to -1 mod 8. A7522

Irregular primes: primes p such that at least one of the numerators of the Bernoulli numbers B₂, B₄, ..., B_p-3 (A000367) is divisible by p. A928

Primes of form 10n+7. A30432

Larger member p+4 of cousin primes (p, p+4). A46132

Positive integers which apparently never result in a palindrome under repeated applications of the function A056964(x) = x + (x with digits reversed). A23108

Primes such that their decimal representations interpreted in base 11 are also prime. A91924
