permutation groups

Permutation groups are mathematical structures that explore the different ways to arrange or reorder a set of items. Imagine you have a set of colored beads, and you want to know how many unique ways you can arrange them. Each unique arrangement is called a permutation. A permutation group captures all possible arrangements of the items and the rules for switching them around. This concept is important in various fields, including algebra, combinatorics, and computer science, as it helps in understanding symmetries, solving puzzles, and developing algorithms.
