OEIS Sequences

First member of a prime quadruple in a 2p-1 progression. A57327

Primes p such that exactly four numbers among all circular permutations of the digits of p are prime. A344628

Primes p such that p's set of distinct digits is {1,3,7}. A108382

Smallest primes starting a complete three iterations Cunningham chain of the second kind. A110024

Number T(n,k) of permutations p of [n] such that k is the maximum of the partial sums of the signed up-down jump sequence of 0,p; triangle T(n,k), k>=0, k<=n<=k*(k+1)/2, read by columns. A316293

Let p = n-th prime, then a(n) = smallest prime having p as its least prime primitive root. A84739

Lexicographically largest increasing sequence of primes for which the continued square root map (see A257574) produces π. A257582

Smallest primes starting a complete three iterations Cunningham chain of the first or second kind. A110025
