OEIS Sequences

Primes having only {1, 6, 7} as digits. A260891

Primes that are a concatenation of 7, 11 and a prime. A101250

Intersection of A013917 and A071150. A255017

a(1) = 2, a(2) = 1. For n >= 3, a(n) is found by concatenating the cubes of the first n-1 terms of the sequence in reverse order and then dividing the resulting number by a(n-1). A181870

Integers whose decimal expansion satisfies the condition that if we read each term from the left to right (the most significant to the least significant digit) then each nonzero digit gives a distance to the next nonzero digit to right (with a cyclic wrap-over from the least-significant to the most significant nonzero digit). A71161

Greatest k <= n such that 3ⁿ + 3^k - 1 is prime, or 0 if no such prime exists. A181530
