In Mathematics, there are numerous types of groups. Two commonly studied types of groups are:

1. Finite Groups: A finite group is a group that has a finite number of elements. In other words, it has a specific and countable number of elements. The set of elements in a finite group can be combined using an operation that satisfies the four group axioms: closure, associativity, identity element, and inverse element. Examples of finite groups include the cyclic group, symmetric group, dihedral group, and quaternion group.

2. Infinite Groups: Unlike finite groups, infinite groups have an infinite number of elements. These groups can also be combined using an operation that satisfies the group axioms. Infinite groups can be further categorized into countable and uncountable groups. Countable infinite groups have elements that can be enumerated, while uncountable infinite groups have elements that cannot be fully counted or enumerated. Examples of infinite groups include the group of integers under addition, the group of real numbers under addition, and the group of invertible matrices under matrix multiplication.

These two types of groups, finite and infinite, form the fundamental building blocks of group theory, a branch of abstract algebra that studies the properties and structures of groups.
