What is a grouping of things without reguard to their order?

A grouping of things without regard to their order is called a set. In mathematics, a set is defined as a collection of distinct objects, considered as an object in its own right. The elements within a set are typically not arranged in any specific sequence, and the focus is on the presence or absence of items rather than their arrangement. For example, the set {Apple, banana, cherry} is the same as {cherry, Apple, banana}.
