Positions of second occurrences of n in A165634: A165634(a(n))=n. [From Reinhard Zumkeller (reinhard.zumkeller(AT)gmail.com), Sep 23 2009]
a(n) = b(n)-th highest positive integer not equal to any a(k), 1 <= k <= n-1, where b(n) = primes = A000040(n). a(1) = 2, a(n) = a(n-1) + A000040(n) - A000040(n-1) + 1 for n >= 2. a(1) = 2, a(n) = a(n-1) + A001223(n-1) + 1 for n >= 2. a(n) = A014688(n) - 1.
