• n*10^4-1, n*10^4-3, n*10^4-7 and n*10^4-9 are all prime.at n=10A064978
• 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=38A366253
