The Dehn–Sommerville equations are a set of relationships in combinatorial geometry and convex geometry that relate the combinatorial properties of convex polytopes (or more generally, simplicial complexes) to their face counts. Specifically, these equations describe how the numbers of faces of different dimensions of a convex polytope are interconnected.
