15.1: Cyclic Groups - Mathematics LibreTexts
If G is a cyclic group of order n and a is a generator of G, the order of ka is n/d, where d is the greatest common divisor of n and k. Proof.
What makes something Even or Odd? - Mathematics Stack Exchange
If n is odd n+a must be even, because n is representable as k+k+a by definition thus n+1 is representable as k+k+a+a. Since all cyclic groups ...
Every finite cyclic group of order n is isomorphic to the additive group of Z/nZ, the integers modulo n. Every cyclic group is an abelian group (meaning that ...

Prove that every subgroup of a cyclic group is cyclic - GeeksforGeeks
Proof : Let us suppose that G is a cyclic group generated by a i.e. G = {a}. If another group H is equal to G or ...
