... Let h ∈ G such that h ∗ g = e, and g −1 ∈ G such that g ∗ g −1 = e. Then h ∗ g ∗ g −1 = h ∗ (g ∗ g −1 ) = h ∗ e = h. Also h ∗ g ∗ g −1 = (h ∗ g) ∗ g −1 = e ∗ g −1 = g −1 . Therefore, h = g −1 . Lemma 2 (Uniqueness of identity). Let G be a group, with identity e. Suppose there exists e0 ∈ G such that ...
