Though the product description does not explicitly say it, this book is a collection of the end-of-chapter problems in Group Theory in Physics with solutions. Consequently, the problems make frequent references to definitions, axioms, and theorems in Group Theory in Physics, and the solutions follow its notation. This limits the usefulness of this book unless you own the other one also. Instructors using Group Theory in Physics as a textbook should be aware of the existence of this book since using the end-of-chapter problems as homework would be pointless.
