Properties

Appears in sequences

• a(1) = a(2) = 1. For n >=3, a(n) = the a(n-2)th integer, among those positive integers which are missing from the first (m-1) terms of the sequence, below a(n-1) if such a positive integer exists. Otherwise, a(n) = the a(n-2)th integer, among those positive integers which are missing from the first (m-1) terms of the sequence, above a(n-1).at n=43A118627
• Primes p such that q-p = 40, where q is the next prime after p.at n=32A126721
• G.f.: Sum_{n>=0} x^n * ((1+x)^n + sqrt(3)*i)^n / (1 + sqrt(3)*i*x*(1+x)^n)^(n+1), where i^2 = -1.at n=9A323683
