Web2. Groups of Order 4 Theorem 2.1. Any group of order 4 is isomorphic to Z=(4) or Z=(2) Z=(2). Proof. Let G have order 4. Any element of G has order 1, 2, or 4. If G has an element of order 4 then G is cyclic, so G ˘=Z=(4) since cyclic groups of the same order are isomorphic. (Explicitly, if G = hgithen an isomorphism Z=(4) !G is a mod 4 7!ga.)

Webn is cyclic. It is generated by 1. Example 9.3. The subgroup of {I,R,R2} of the symmetry group of the triangle is cyclic. It is generated by R. Example 9.4. Let R n = {e 2⇡ik n k =0,1...n1} be the subgroup of (C⇤,·,1) consisting of nth roots of unity. This is cyclic. It is generated by e2⇡i n. We recall that two groups H and G are ... A cyclic group is a group which is equal to one of its cyclic subgroups: G = g for some element g, called a generator of G . For a finite cyclic group G of order n we have G = {e, g, g2, ... , gn−1}, where e is the identity element and gi = gj whenever i ≡ j ( mod n ); in particular gn = g0 = e, and g−1 = gn−1.
