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.) WebA cyclic group G G is a group that can be generated by a single element a a, so that every element in G G has the form ai a i for some integer i i . We denote the cyclic group of order n n by Zn Z n , since the additive group of Zn Z n is a cyclic group of order n n. …

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. ctbh 25 https://procus-ltd.com

WebExample: This categorizes cyclic groups completely. For example suppose a cyclic group has order 20. Every subgroup is cyclic and there are unique subgroups of each order 1;2;4;5;10;20. If Ghas generator gthen generators of these subgroups can be chosen to be g 20=1 = g20, g 2 = g10, g20=4 = g5, g20=5 = g4, g20=10 = g2, g = grespectively. WebThis exercise describes 13 isomorphism types of groups of order 56. (a) Prove that there are 3 abelian groups of order 56. Solution: From HW 2, Problem 2, we know that every finite abelian group has a unique de- composition as the product of cyclic groups in invariant factor form. 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.

The group U12 has four elements: 1,5,7,11. By direct computation the square of each element is 1. But a cyclic group of order 4 must have an element of order 4. Hence the group is not cyclic. 2. a) Show that the group Z12 is not isomorphic to the group Z2 ×Z6. b) Show that the group Z12 is isomorphic to the group Z3 ×Z4. Solution.
