• Shiraishi numbers: a parametrized family of solutions c to the Diophantine equation a^3 + b^3 + c^3 = d^3 with d = c+1.at n=34A226903
• Number of length-4 0..n arrays with no repeated value differing from the previous repeated value by one.at n=13A269495
• Related to the set of Motzkin trees where all leaves are at the same unary height 2.at n=22A321572
• 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 regions in the resulting planar graph.at n=49A367304
