- Denominators of continued fraction convergents to sqrt(371).at n=10A041703
- a(n) is the least prime p, such that next_prime(2*p) - 2*p = 2*n - 1.at n=34A059846
- Numbers k such that 7*10^k - 11 is prime.at n=21A102740
- Primes with digit sum = 38.at n=17A106772
- Triangle read by rows. Let g(n) = n if n is a prime, otherwise g(n) = 1. Let p(0) = 1, p(n) = g(n)*p(n-1). Row n gives coefficients of Product_{j=0..n} (x - p(j)), with row 0 = {1}.at n=47A118686
- Primes of the form 10n^2+6n+1.at n=32A154409
- Primes that become squares when prefixed with an 8.at n=9A167741
- Primes which become palindromic primes when the digits are rotated once to the left.at n=27A234912
- Least prime p such that pi(p*n)^2 + 1 = prime(q*n) for some prime q.at n=31A260219
