Does abelian imply cyclic
WebH is unique. ♦ (Note:) In a cyclic group of order n, xar = xbr ⇒ ar ≡ br (mod n) but it does not imply a = b, even mod n. 8 Chapter 2.2 Problem 20 (a) Let a,b ∈ G, an abelian group, with orders m,n respectively. Claim: The order of ab divides the least common multiple of m,n. Proof: Let r be the least common multiple of m,n. Webcyclic subgroup hgihas trivial intersection with the derived subgroup [K;K], of K. Recall that K has derived length d 2 by the assumptions, so K(d 1) [K;K], hence K(d 1) \hgi= f1g. On the other hand, K(d 1) L(d 1) as K L, therefore the rank of the free abelian group K(d 1) must be strictly smaller than the rank of L(d 1), contradicting the ...

That is, it is a set of invertible elements with a single associative binary operation, and it contains an element g such that every other element of the group may be obtained by repeatedly applying the group operation to g or its inverse.
