Witryna1 kwi 2024 · Let G be a finite abelian group and let p be a prime that divides order of G. then G has an element of order p. Proof When G is abelian. First note that if G is prime, then G ≈ Z p and we are done. In general, we work by induction. If G has no nontrivial proper subgroups, it must be a prime cyclic group, the case we’ve already … WitrynaQuestion: Let G be a finite group and let H be a normal subroup of G.

Witrynagroups of order 6.] Solution. Suppose that G is an abelian group of order 8. By Lagrange’s theorem, the elements of G can have order 1, 2, 4, or 8. If G contains an element of order 8, then G is cyclic, generated by that element: G ˇC8. Suppose that G has no elements of order 8, but contains an element x of order 4.

Order of an element divides order of group

WitrynaNow suppose that Gdoes not contain any elements of order 4. Since the order of every element divides 4, the order of every element must be 1, 2 or 4. On the other hand, the only element of order 1 is the identity element. Thus if Gdoes not have an element of order 4, then every element, other than the identity, must have order 2. WitrynaThe order of an element divides the order of the group. The order of the group (Z 11; mod 11) is equal to 10, while order(3) = 5 in (Z 11; mod 11), and 5 divides 10 order(2) = 10 in (Z 11; mod 11), and 10 divides 10 Similarly, order(1) = 1 in (Z 11; mod 11), and 1 divides 10 Since the divisors of 10 are 1, 2, 5, and 10, the element orders can
