• Number of vertex-transitive graphs with n nodes.at n=38A006799
• a(n) = sum of squares of first n odd primes.at n=21A133547
• Number of Cayley graphs on n nodes.at n=38A185959
• Number of nX6 0..1 arrays with every element equal to 1, 2, 4, 6 or 7 king-move adjacent elements, with upper left element zero.at n=9A298658
• The number of regions inside a heptagon formed by the straight line segments mutually connecting all vertices and all points that divide the sides into n equal parts.at n=4A329713
• 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 regions in the resulting planar graph.at n=40A367323
