Geometric Model, Probably by L. Brill or M. Schilling, Projection of a Four-Dimensional Prism
notes: label: Description
content: This is one of several models designed by V. S. Schlegel to represent the projection of four-dimensional surfaces. Specifically, it represents the projection of a four-dimensional triangular prism into three space. Parallel displacement of a tetrahedron (shown at the two ends of the model) along the sides of ta triangular prism in three-space creates the projection. The prism also is divided by threads (all broken here) into four identical five-cells.
