`Elements' does the same as `AsSSortedList', i.e. it returns a sorted list of elements. As comparison of permutations is stable, this list will always be the same, even if you change the generators of W.

(In general, with other commands in GAP the same sequence of commands from the start in the same version of GAP on the same machine will always produce the same output, but this is not neccessarily guaranteed to stay stable over different versions.)
