• Smallest number m such that A247462(m) = n.at n=5A247468
• Values of g-hat_4(n), a sum involving Stirling numbers of the first kind.at n=5A261689
• a(n) = (1/24)*n*((4*n + 3)*(2*n^2 + 1) - 3*(-1)^n).at n=17A325656
• The number of vertices on an octagon formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts.at n=3A333109
• Least b > 1 such that (b^(prime(n)^2) - 1)/(b^prime(n) - 1) is prime.at n=41A353101
• Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of the n*(k+1) boundary points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of vertices in the resulting planar graph.at n=41A367322
• Number of vertices in the hyperoctahedral (or cocktail party) graph of order n.at n=15A368756
• G.f.: Sum_{k>=0} x^k * Product_{j=1..2*k} (1 + x^j)/(1 - x^j).at n=24A385088
