5. Let G be a finite group. A representation p: G + GL(V) is irreducible if the only subrepresentations of p are V and {0}. (a) T/F: Let G = Sn, n > 2, and let p: G+ GL(V) be the permutation representa- tion associated to a basis B of V. Then p is not irreducible. (b) T/F Let G be a finite group with 2 or more elements and let p: G GL(V) be the regular representation of G. Then p is not irreducible. 5. Let G be a finite group.
