OEIS Sequences

a(n) is the smallest prime q such that (r-q)/(q-p) = n, where p<q<r are consecutive primes (or 0 if no such prime exists). A179210

Primes p such that q-p = 36, where q is the next prime after p. A134117

a(n) is the smallest prime q such that, for the previous prime p and the following prime r, the fraction (q-p)/(r-q) has denominator n (or 0, if such a prime does not exist). A168253

Primes p such that p-1 and p+1 are both divisible by fourth powers. A86709

a(1) = 2. For n>1, let s denote the binary string of a(n-1) with the leftmost 1 and following consecutive 0's removed. Then a(n) is the smallest prime not yet present whose binary representation begins with s. A262350

Decimal representation of the x-axis, from the left edge to the origin, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 825", based on the 5-celled von Neumann neighborhood. A284185

Primes introducing new second differences in A036263. A295973

Primes that remain prime through 3 iterations of function f(x) = 3x + 8. A23279

Primes in which the unit place digit is 1 and the k-th most significant digit is prime (2,3,5,7) if k is prime else is composite (4,6,8,9,0). A89704
