Combinatorial map

A combinatorial map is a mathematical structure used primarily in the field of topology and combinatorial geometry. It provides a way to represent and manipulate geometrical objects, particularly in the context of surfaces and subdivision of spaces. The main features of a combinatorial map include: 1. **Vertex-Edge-Face Representation**: Combinatorial maps describe the relationships between vertices (0-dimension), edges (1-dimension), and faces (2-dimension).
