Problem 42.4

Let .G; / be a group and suppose H is a nonempty subset of G. Prove that .H; / is a subgroup of .G; / provided that H is closed under and that for every g 2 H, we have g 1 2 H. This gives an alternative proof strategy to Proof Template 24. You do not need to prove that e 2 H. You need only prove that H is nonempty. 42.
