Appears in sequences

• Numbers k whose decimal representation, read as a base-22 value and divided by k, yields an integer.at n=30A032575
• Bisect A053445 then calculate the first differences of the resulting sequence.at n=39A160643
• Number of maximal matchings in the n-triangular honeycomb queen graph.at n=4A289878
• Number of ways to write n as an ordered sum of eight positive Fibonacci numbers (with a single type of 1).at n=27A357716
• Place n points in general position on each side of a square, and join every pair of the 4*n+4 boundary points by a chord; sequence gives number of edges in the resulting planar graph.at n=7A367122
• 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 edges in the resulting planar graph.at n=37A367190
