The first main goal of the Atlas software package is to make available all the structural data about reductive groups that is required for representation theory. Let G be a connected complex reductive algebraic group, with a fixed chosen inner class. The following structural data are currently available for G :
It should be stressed that all this information is computed, not looked up in databases. The only input that the program requires is the root datum for G (which is constructed during the initial user interaction), and the choice of inner class.
