Enumerating Foldings and Unfoldings between Polygons and Polytopes
arXiv:cs/0107024
Abstract
We pose and answer several questions concerning the number of ways to fold a polygon to a polytope, and how many polytopes can be obtained from one polygon; and the analogous questions for unfolding polytopes to polygons. Our answers are, roughly: exponentially many, or nondenumerably infinite.
