Concentrates on how to make predictions about the numbers of each kind of basic state of a quantum system from only two ingredients: the symmetry and linear model of quantum mechanics

Method has wide applications in crystallography, atomic structure, classification of manifolds with symmetry and other areas

Engaging and vivid style

Driven by numerous exercises and examples

Systematic organization

Separate solutions manual available
