How to input a vector of group generators?

In order to enter a vector, first enter '[', then enter the elements of the vector seperated by commas, and finally enter ']'. Since the entries of the vector are permutations you must know how to input a permutation.

For instance the generators of the symmetric group of three elements could be entered as [[2,3,1],[2,1,3]]. (All generators must be permutations of the same length!).
