notes: label: Description
content: The center of this cut and folded brown paper model is a surface like MA.304723.627. Attached symmetrical at the top and the bottom are identical polyhedra, both with three double points. Each of the points has a triangle and two trapezoids for sides, with an additional trapezoid toward the center. Hence each extension has six trapezoids and four triangles. To find the total number of faces, one would multiply this figure by six, add the faces associated with the center, and deduct for coplanar polygons.
