In geometry, a skewapeirohedron is an infinite skew polyhedron consisting of nonplanar faces or nonplanar vertex figures, allowing the figure to extend...
finitely many times. In addition to the planar regular polygons there are infinitely many regularskew polygons. Skew polygons can be created via the blending...
specify how many cells exist around the edge. It is related to a skewapeirohedron with vertex configuration 4.4.6.6, with the octagons and some of the...
tetrahedrille, also called a disphenoid tetrahedral honeycomb. Although a regular tetrahedron can not tessellate space alone, this dual has identical disphenoid...
