1) Choose a subgroup of Pentagons D₅, and list all the left or right cosets of your pet. Will the set of right cosets be different from the left cosets? Explain.

2) Does Pentagons D_5, have any non-trivial normal subgroups? If so, give an example.If not, explain why not.

3) Is there a second binary structure that would make Pentagons D₅ a ring?

1. Prove``The left and right cosets partition G into equal sized chunks." (Cor 5.11 and 5.13 in your book). You have to show the ~ is an equivalence relation, you can't just cite a theorem from the book. Similarly so you have to show phi is 1-1 and onto, you can't just cite a theorem from the book.
