Beschreibung
This textbook provides an introduction to group theory starting from the basics, relying on geometry to elucidate its various aspects.
Groups naturally manifest as symmetries of geometric shapes, such as reflections and rotations. The book adopts this perspective to provide a straightforward, descriptive explanation, supported by examples and exercises in GAP, an open-source computer algebra system. It covers all of the key concepts of group theory, including homomorphisms, group operations, presentations, products of groups, and finite, abelian, and solvable groups. The topics include cyclic and symmetric groups, dihedral, orthogonal, and hyperbolic groups, as well as the significant notion of Cayley graphs.
Self-contained and requiring little beyond high school mathematics, this book is aimed at undergraduate courses and features numerous exercises. It will also appeal to anyone interested in the geometric approach to group theory.

“This textbook is designed to teach beginning students group theory using geometry as the motivating force while also relying heavily on the computer software package GAP. This overall design is nicely motivated and well used throughout the text. ... One particularly nice feature of this book is that each individual section is followed by a short batch of well-chosen exercises that immediately reinforce new topics.” (John J. Watkins, Mathematical Reviews, May, 2026)
