Yes, and moreover, I want the polyhedron to be flattenable to an ordinary rectangle. (Though I suppose that if one can reduce the number of faces by dropping this constraint, that'd be worth knowing.) Jim On Fri, Oct 30, 2015 at 5:51 PM, Dan Asimov <dasimov@earthlink.net> wrote:
I suppose this question is about a Moebius strip embedded in R^3 as a polyhedron (a union of planar triangles that can intersect pairwise in only an edge, a vertex, or the empty set. Yes?

P.S. Please note correct spelling of Moebius (unless you can use an umlaut).

In a similar vein we can ask, What's the smallest possible number of faces a Mobius strip can have? You are permitted to use a rectangle of any aspect ratio you like.
