Group Theory

From this page you can access a collection of materials dealing with some important areas of Group Theory. For Maynooth University students, this material is typically covered in parts of Groups (MT316A). These resources are not a replacement for the material covered in your lectures and assignments, rather you should use them as extra support to aid your understanding of any material you may have difficulties with.
