Geometric Model by A. Harry Wheeler, Cuboctahedron Fourth Species

Geometric Model by A. Harry Wheeler, Cuboctahedron Fourth Species

<< >>
Usage conditions apply
Wheeler designed several models that extended the cuboctahedron (a model with eight triangular and six square faces). This is what he called the “fourth species” of the cuboctahedron. It has eight regions that are triangular pyramids facing inward and hence contribute three triangular sides each. It also has six regions that contribute eight triangular sides each. Finally, twelve more open regions have two square and two triangular sides. Many sides appear to be coplanar.
A mark on the model reads: Cuboctahedron (/) Fourth Series (/) A. Harry Wheeler (/) July-19-1932. A pencil mark reads: 13 / 38 (/) RS30.
Compare MA.304723.072 and MA.304723.073. They are not identical.
