Question
In this problem, consider the group G = S3 acting on X = S4 by conjugation.
In other words, given an element g E S3 (thought of as a permutation of {1, 2, 3})
and an element x E S4 (thought of as a permutation of {1, 2, 3, 4}), the action is
defined by
g •x = gxg¬!.
For example, (12) · (34) = (12)(34)(12)-1 = (34).
Answer the following, being sure to carefully justify your answers.
(a) Describe the orbit Orbg((14)), and the stabiliser Stabg((14)).
(b) Is the action faithful?
(c) How many distinct orbits are there in X?
