If G is finite, we say that (G, o) is a finite group. Otherwise, it is called an infinite group. (Z, +) is an infinite group as the number of elements of Z is not finite. (Z/2Z, +) is a finite group of order 2. Types of Groups There are many types of groups. For example,
In mathematics, the order of a finite group is the number of its elements. If a group is not finite, one says that its order is infinite.
