 Symmetries form the basis of the packages DSolve and PDSolve1. A knowledge of symmetries facilitates the understanding and analysis of solutions of differential equations and an understanding of the techniques used to solve the equations. This article introduces a package, MathSym, that assists in the computation of symmetries. MathSym's flexibility and utility are illustrated through four examples, two from ordinary differential equations and two from partial differential equations.
