Symmetric Groups

1. Show that for all .
2. Show that if is prime, where is any transposition and is any p-cycle.
3. Show that is a proper subgroup of . What is the isomorphism type of this subgroup?

It seems like if I could do 1, then 2 and 3 would follow pretty easily...I'm not sure.

Re: Symmetric Groups
