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


This cut, folded, and glued paper model is in the general shape of a cuboctahedron. , However, all six of the triangular sides have been replaced by facets with three triangular sides. . A paper tag on the model reads: 664. Another mark reads: ROBERT CURTIS (/) OCT 22, 1938. Three small fragments exist that made up most of one side and part of two others.

Wheeler described this model as a one sided polyhderon "derived from Archimedean Solid VII. Bruckner page 132. He also assigned it his number M23.
