A permutation group is a finite group \(G\) whose elements are permutations of a given finite set \(X\) (i.e., bijections \(X \longrightarrow X\)) and whose group operation is the composition of permutations.The number of elements of \(X\) is called the degree of \(G\).. In Sage, a permutation is represented as either a string that …
