The LIESUPER package for REDUCE. liesuper.web: We will describe a REDUCE package for symbolic computations in (free) Lie (super)algebras. For this purpose we will introduce a new rtype liebracket, which satisfies the bilinearity and the (graded) skew-symmetry of the liebracket. Moreover, we will implement a mechanism to check the (graded) Jacobi identity and add sufficient bells and whistles to facilitate the usage of various kinds of gradings.
