Primes p such that p + 4 is also prime. A23200

a(n) = a(n-1) + a(n-4) with a(0) = 0, a(1) = a(2) = a(3) = 1. A3269

Primes whose reversal in base 10 is also prime (called "palindromic primes" by David Wells, although that name usually refers to A002385). Also called reversible primes. A7500

Prime(n), where n is such that (1+∑_i=1..n prime(i)) / n is an integer. A233523

Y-toothpick sequence (see Comments lines for definition). A160120

Record gaps between primes (upper end) (compare A002386, which gives lower ends of these gaps). A101
