# Topology#

Sage includes some tools for topology, and in particular cell complexes: (filtered) simplicial complexes, \(\Delta\)-complexes, cubical complexes, and simplicial sets. A class of generic cell complexes is also available, mainly for developers who want to use it as a base for other types of cell complexes.
