Abstract We prove that if an n -dimensional space X satisfies certain topological conditions then any triangulation of X as well as any its representation as a simplicial set with contractible faces has at least 2ⁿ 2 n faces of dimension n. One example of such X is the n -dimensional torus (S¹) ⁿ (S 1) n.
