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 D5, 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?
