In this video, we prove properties about cyclic groups, their subgroups, and their orders. In particular, we prove that the subgroups of a cyclic group and in one-to-one correspondence of the divisors of the order of the group.

There is a wonderful balance amongst theory, proof, explanation and examples. Most professors don't have this balance, and hence are poor teachers. All these lectures harmonise beautifully. Your students are fortunate! Thank you
