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:

• 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.
