Every subgroup of a cyclic group is characteristic. Let G = <a> = {a^ : nez} and C≤G. s.t. c=<am>. Let z€4(c) = {4(x): XEC}, so that x=(4) ?, q€ ... |
A subgroup H of a group G is called characteristic in G if for any φ∈Aut(G), we have φ(H)=H. In words, this means that each automorphism of G maps H to itself. |
