OEIS Sequences

Numbers such that every cyclic permutation is a prime. A68652

Circular primes that are not repunits. A293663

Square array A(n, k), read by antidiagonals downwards: k-th prime p such that cyclic digit shifts produce exactly n different primes. A317716

The smallest representative in a cycle of circular primes, where circular primes are numbers that remain prime under cyclic shifts of digits. A16114

Geometric mean of the digits = 3. In other words, the product of the digits is = 3^k where k is the number of digits. A61427

Primes p such that p1 = ceiling(p/2) + p is prime and p2 = floor(p1/2) + p1 is prime. A158714

Primes p such that exactly five numbers among all circular permutations of the digits of p are prime. A344629

Primes p such that p's set of distinct digits is {1,3,9}. A108383

Primes of the form 2·n²+26·n+11. A243888

a(n) = smallest prime p for which cyclic digit shifts produce exactly n different primes, or 0 if no such p exists for n. A247153
