# Sylow's Theorem

A) Prove there is no simple group of order 200.

b) Assume that a group G has two Sylow p-subgroups K and H. Prove that K and H are isomorphic.

c) Show that a group G of order 2p^n has proper normal subgroup, where p is odd prime number and n > 0.

#### Solution Preview

a) Proof:

Since the group G has order 200 = 2^3 * 5^2, we consider its Sylow 5-subgroup. According to Sylow's

Theorem, the number of its Sylow 5-subgroup is 5k+1 | 2^3 = 8. Then the only possibility is k = 0.

So G has unique Sylow 5-subgroup and hence it must be ...
