notes: label: Description
content: The dimensions given are for each of these six plaster models. All of them are eleven-sided polyhedra. Three models are identical and the other three are mirror images of the first. Each model has a hexagonal top, six square faces, and six triangular faces (in two sizes). Some of the markings are in color. Various faces and parts of faces are marked S, C, underlined S, or doubly underlined S, indicating faces they adjoin which are either parts of congruent pieces or mirror image pieces. This model resembles number #325 in the Göttingen collection. The Göttingen model has a total of two blocks and sixteen pieces.
label: Description
content: This is part of a series of models designed by A. Schoenflies in Göttingen to illustrate the regular partition of space. Schoenflies designed “stones” like these which could be arranged into larger blocks (sometimes with congruent stones and sometimes using stones that were mirror images of one another). The series was first published by Brill in 1891.
label: Description
content: This example of the model was exhibited at the Columbian Exposition, a World’s Fair held in Chicago in 1893.
