In (polyhedral) geometry, a flag is a sequence of faces of a polytope, each contained in the next, with exactly one face from each dimension. More formally, a flag ψ of an n-polytope is a set {F–1, F0, ..., Fn} such that Fi ≤ Fi+1 and there is precisely one Fi in ψ for each i,. Since, however, the minimal face F–1 and the maximal face Fn must be in every flag, they are often omitted from the list of faces, as a shorthand. These latter two are called improper faces. For example, a flag of a polyh
