👉 In mathematics, a square tail is a term used to describe a type of combinatorial object. This combinatorial object is defined as follows: 1. A square tail (also known as a combinatorial tail) is an object with a finite number of elements that can be arranged in a way such that each element appears exactly once, and the order in which they appear matters. 2. The term "square" refers to the fact that the combinatorial object has 4 sides
