OEIS Sequences

Place n equally spaced points on each side of an equilateral triangle, and join each of these points by a chord to the 2·n new points on the other two sides: sequence gives number of vertices in the resulting planar graph. A366483

a(n) = binomial(n+2,2) * binomial(n+7,2). A104676

Sum of cubes of divisors is a square. A63831

Table read by antidiagonals: Place k equally spaced points on each side of a regular n-gon and join every pair of these n·k points by a chord; T(n,k) (n >= 3, k >= 0) gives the number of vertices in the resulting planar graph. A367302

Number of nonempty subsets of {1,2,...,n} in which exactly 1/4 of the elements are <= n/3. A47196
