WebSince f is surjective, there exist g, h ∈ G such that x = f ( g), y = f ( h); WLOG, we may assume h ≠ e G. (Why?) Suppose, for a contradiction, that G is cyclic. Then g = h k for some integer k. But then x = f ( g) = f ( h k) = ( f ( h)) k = y k. Hence G is not cyclic. Share Cite answered Apr 4, 2024 at 20:43 Shaun 42k 18 62 167 Add a comment
