Abstract Algebra 6: center of a group, centralizers and cyclic subgroups

In this sixth video we will talk about the notions of center of a group (denoted Z(G)), the centralizer of an element of a group, the notion of order of an element and of cyclic subgroup generated by an element.
We will also give some more examples of subgroups and prove some more results about groups and abelian groups.
