On Gale and braxial polytopes
Margaret M. Bayer, Tibor Bisztriczky
Cyclic polytopes are characterized as simplicial polytopes satisfying Gale's evenness condition (a combinatorial condition on facets relative to a fixed ordering of the vertices).…

On braxtopes, a class of generalized simplices
Margaret M. Bayer, Tibor Bisztriczky
In a d-simplex every facet is a (d-1)-simplex. We consider as generalized simplices other combinatorial classes of polytopes, all of whose facets are in the class. Cubes and multip…
