• Sequence A001033 gives the numbers n such that the sum of the squares of n consecutive odd numbers x^2 + (x+2)^2 + ... +(x+2n-2)^2 = k^2 for some integer k. For each n, this sequence gives the least value of k.at n=27A056132
• Number of 3-element antichains on an unlabeled n-element set; equivalence classes of monotone Boolean functions of n variables with 3 mincuts under action of symmetric group S_n.at n=17A056778
• Prime index of A000101(n), maximal gap upper end prime index.at n=17A107578
• a(n) = 2*n^3 - 4*n^2 + 6*n - 2 (n>=1).at n=27A304159
• Expansion of e.g.f. P(P(x)), where P(x) = Sum_{k>=1} prime(k)*x^k/k!.at n=5A316186
