Action -- the class of all finite group actions

Types of Action :

• ActionOnComplex -- the class of all finite group actions on complexes
• ActionOnGradedModule -- the class of all finite group actions on graded modules

Functions and methods returning an object of class Action :

• action -- define finite group action

Methods that use an object of class Action :

• "actors(Action)" -- see actors -- group elements of an action
• "inverseRingActors(Action)" -- see inverseRingActors -- get inverse of action on ring generators
• net(Action) -- format for printing, as a net
• "numActors(Action)" -- see numActors -- number of acting elements
• ring(Action) -- get ring of object acted upon
• "ringActors(Action)" -- see ringActors -- get action on ring generators
• target(Action) -- get object acted upon

For the programmer

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