Geometric Model by A. Harry Wheeler, One-Sided Polyhedron
name: label: maker
content: Wheeler, Albert Harry
notes: label: Description
content: This paper model has tetrahedral symmetry. The equilateral triangles of a a regular tetrahedron are cut away to form a figure with an equilateral triangle at the center, a smaller equlateral triangle at each vertex of each of these, and four rectangles with part of their sides along the edges of equilateral triangles. In lieu of the vertices of a regular tetrahedron, the model has triangular facets, with each triangle of a facet coplanar with a rectangle.The four figures at the corners resemble faceted octahedra.
label: Description
content: A paper tag on the model reads: 660.
label: Description
content: In his list of models, Wheeler described model 660 as an "Octahedral Polyhedron Inscriptible in a Regular Tetrahedron" and compared it to his model 659. Another model in the collections, with museum number MA.304723.369, also is marked 660. It is not identical to this model. It is more similar to model MA.304723.372, which is labeled with Wheeler's number 659.
