# maxPolyhedra -- displays the generating Polyhedra of a PolyhedralComplex

## Synopsis

• Usage:
L = maxPolyhedra PC
• Inputs:
• Outputs:

## Description

maxPolyhedra displays the List of generating polyhedra of the PolyhedralComplex, i.e. all Polyhedra that are not a face of one of the other Polyhedra. These are all of the same dimension if and only if the PolyhedralComplex is pure (see: isPure).
