  Finite group actions on free resolutions and modules arise naturally in many
interesting examples. Understanding these actions amounts to describing the
terms of a free resolution or the graded components of a module as group
representations which, in the non modular case, are completely determined by
their characters. With this goal in mind, we introduce a Macaulay2 package for
computing characters of finite groups on free resolutions and graded components
of finitely generated graded modules over polynomial rings.
