Geometric Model by R. L. Curtis, a Student of A. Harry Wheeler, One-Sided Polyhedron


This cut, folded and glued paper model has tetrahedral symmetry. The model appears to be the union of four faceted octahedra (also called heptahedra or tetrahemihexahedra - models like MA.304723.380).

A mark on the model reads: 662. Another mark reads: Curtis 10/18/38.

Wheeler referred to this model as being from Brűckner VIII – 36. He gave it the additional number M21.

Compare models MA.304723.415 and MA.304723.391. They are not identical
