ActionOnComplex -- the class of all finite group actions on complexes

Functions and methods returning an object of class ActionOnComplex:

• action(ChainComplex,List) -- see action(ChainComplex,List,List,ZZ) -- define finite group action on a resolution
• action(ChainComplex,List,List,ZZ) -- define finite group action on a resolution

Methods that use an object of class ActionOnComplex:

• actors(ActionOnComplex,ZZ) -- group elements of action on resolution
• character(ActionOnComplex) -- compute all Betti characters of minimal free resolution
• character(ActionOnComplex,ZZ) -- compute Betti characters of minimal free resolution
• ActionOnComplex == ActionOnComplex -- see Equality checks -- compare actions and characters

For the programmer

The object ActionOnComplex is a type, with ancestor classes Action < HashTable < Thing.
