3. Let G be a finite group, and suppose that N is a normal subgroup of G. Suppose that P is a p-Sylow subgroup of N. (This will not necessarily be a p-Sylow subgroup of G.) Suppose that P is normal in N. Prove that P is normal in G. (This should be short... just be clear in your proof.)

I need help with number 3
(f) Use Sylow's Theorem to show why every 8-cycle is contained in some 2-Sylow subgroup,
and why every 2-Sylow subgroup of S8 has to contain an 8-cycle.
(g) Find an 8-cycle in the 2-Sylow subgroup I described for you! Explain your answer.
