Geometric Model by A. Harry Wheeler, One-Sided Polyhedron
name: label: maker
content: Wheeler, Albert Harry
notes: label: Description
content: This plastic model has three points that each are surrounded by four triangular pieces. It also has a point surrounded by three quadrilaterals on top and one surrounded by six triangles on the bottom, and three points on the sides at which three triangles and a quadrilateral meet. In fact, each quadrilateral on top is coplanar with two triangles on top. Each triangle on the bottom is coplanar with one other triangle on the bottom. This reduces the number of faces to six, the number of edges to twelve, the number of vertices to seven, and the number of faces to six. A mark on the model reads: 644 (/) e = 7 (/) K = 12(/) f = 6 (/) e – k + f = 1. Wheeler classified this model as M3 in his series of one-sided polyhedra.
