SymmetryApp© is a JAVA program designed to help students learn about symmetry elements and their operations, both of which are critical to a solid understanding of molecular symmetry and group theory.  The program is not a tutorial.  User input is required to define the symmetry elements and means are available to allow these elements to be positioned anywhere in a molecule.  Once the user has defined a symmetry element, the program executes the symmetry operation and generates a graphics image that allows the user to see firsthand the consequence of their choice.
