Geometric Model by D. Pitts, Truncated Trapezoidal Hexecontrahedron

<< >>
Usage conditions apply
According to the donor, this model is made of Brazilian satinwood and dyed black wood (a sheet of veneer). The sixty wooden sides are truncated faces of a trapezoidal hexecontahedron. When squares were substituted for the normal trapezoids, it left windows in the normally closed figure. The model has thirty rhombic windows, twenty triangular windows and twelve pentagonal windows. Each side has diagonals and a small square marked on it, both on the inside and the outside of the ball.
For a model of a hexecontahedron (without windows) see 304723.283.
