Properties

Appears in sequences

• a(1) = 2; a(n) = smallest prime > a(n-1) such that the sum of any three nondecreasing terms, chosen from a(1), ..., a(n-1) and a(n), is unique.at n=23A060276
• Records in A134204.at n=36A133244
• a(n) = smallest prime q > a(n-1) such that 2*prime(n)*q^prime(n)+1 is also prime.at n=16A225747
• Number of compositions of n avoiding any 3-term arithmetic progression.at n=25A238569
• Primes having only {1, 4, 6} as digits.at n=24A260269
• Primes p such that p^8 - 1 has 384 divisors.at n=9A342064
• Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n*k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of internal vertices in the resulting planar graph.at n=48A367303
• Prime numbersat n=4773
