👉 In geometry and related fields, a subpolygonal set is a subset of a polygon that includes all its vertices. This concept is particularly important in combinatorics, where it refers to sets of points that are connected by line segments and meet at right angles. A subpolygonal set can be defined as follows: - A subpolygonal set is a collection of points that are contained within a larger polygon (also known as the "supercell"). - Each point in this set must lie
