OEIS Sequences

Primes having only {0, 1, 9} as digits. A199329

a(n) is the smallest prime which, if used to start a Euclid-Mullin sequence (like A000945), the resulting sequence contains the n consecutive primes 2, 3, ..., prime(n). A93777

Primes p used as initial values for Euclid-Mullin sequences (variant A000945) instead of 2, such that all provide {p,2,3,5,7,11,13,q,...} initial segments in which the first six primes occur from 2nd to 7th terms. A93778

Start with 1 and repeatedly reverse the digits and add 36 to get the next term. A118536

Primes A005382(n) + A005384(n) - 1 with a twin prime A005382(n) + A005384(n) + 1. A99109
