• Harmonic mean of digits is 6.at n=33A062184
• Antidiagonal sums of A163280.at n=41A163983
• a(n) = a(n-1) + 12*a(n-2) with a(1) = 1 and a(2) = 2.at n=8A290124
• Table read by antidiagonals: Place k points in general position 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 number of regions in the resulting planar graph.at n=40A366253
