OEIS Sequences

a(1) = 1; a(n+1) is the smallest number > a(n) which differs from it at every digit. A68860

Partial sums of A164095. A164096

a(1) = 1; thereafter a(n) is always the smallest integer > a(n-1) not leading to a contradiction, such that any six consecutive digits in the sequence sum up to a prime. A152606

The sequence alternates even and odd integers but also even and odd digits; it is monotonically increasing and a(n) is always the smallest integer fitting the pattern. A137667

Numbers n such that n and the 6 successive integers yield primes if substituted for·in polynomial 5x²+5x+1. A90101
