A zonohedron is a polyhedron in which every face is centrally symmetric (having a center of inversion in two dimensions). This Demonstration shows a one-parameter family of zonohedra with 14 faces generated by an angle variable between 0 and ?/2.

The number 17 is a Fermat prime, which means it is of the form 2^2^n+1, with n=2. In 1796, Gauss discovered that regular polygons with a Fermat number of sides can be constructed using only a straight edge and compass [1]. Gauss showed, in particular, t...
