Web3. Groups of Order 6 To describe groups of order 6, we begin with a lemma about elements of order 2. Lemma 3.1. If a group has even order then it contains an element of order 2. Proof. Call the group G. Let us pair together each g 2G with its inverse g 1. The set fg;g 1ghas two elements unless g = g 1, meaning g2 = e.
