Im lost on this one for abstract algebra, please assist me. Action by conjugation

1.7. Let G be a group and let G act on itself by conjugation. For a E G, denote Og the orbit of
a under conjugation action. The orbits under the conjugation action are called the
conjugacy classes of G. Recall that the action by conjugation on G is given by ga =
gag-1, for g, a e G (Hint: Find the kernel for this particular action (by conjugation), not just
any action.)
(a) Find the kernel of the induced permutation representation p: G – Sg.
