A cyclic group of prime-power order is indecomposable. Let A be cyclic of order pk where k 1. If A = B C where B and C are nontrivial subgroups of A then B and C have p-power order greater than 1 and thus B and C each contain a subgroup of order p (a subgroup of a cyclic group is cyclic and a cyclic group of order n has an element

[Solved] Is a group of prime-power order always abelian?

WebSince automorphisms permute elements of the same order, we can conclude that every element in F has the same order. But a finite group in which all non-identity elements have the same order is necessarily a p -group such that every element has prime order. This can be shown by Cauchy's Theorem.

WebMay 5, 2024 · Every finite abelian group is an internal group direct product of cyclic groups whose orders are prime powers . The number of terms in the product and the orders of the cyclic groups are uniquely determined by the group. Proof Let G be a finite abelian group . In mathematics, specifically group theory, given a prime number p, a p-group is a group in which the order of every element is a power of p. That is, for each element g of a p-group G, there exists a nonnegative integer n such that the product of p copies of g, and not fewer, is equal to the identity element. The orders of different elements may be different powers of p. Abelian p-groups are also called p-primary or simply primary.
