GTPACK

GTPack is the free Mathematica group theory package. GTPack builds a bridge between computational algebra, university education and modern research. It has wide-ranging applications in condensed matter and solid-state physics, photonics, and quantum chemistry... The application of GTPack is described in the book, Group Theory in Solid State Physics and Photonics: Problem Solving with Mathematica. Furthermore, we provide several tutorials to become familiar with the basic GTPack concepts.
