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. A paper tag reads: 202.
label: Description
content: This model sold by both Victor Brill and his successor Martin Schilling as part of his Series XV, Nr. 7 (Brill model number 202).
