content: The dimensions given those of each of the six white plaster pieces. All of these models are eleven-sided polyhedra. Three models are identical, three others are identical and mirror images of the first. Each model has five triangular, two pentagonal and four quadrilateral faces.
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 pieces and sometimes using stones that were mirror images of one another). The series was first published by Brill in 1891. The plaster pieces that comprise the object with museum number 1985.0112.169 could be arranged to form a block with museum number 1985.0112.164. The pieces are marked with the letters S and C, indicating whether they adjoin congruent or mirror image stones. A model of this block and pieces at the University of Göttingen (#324 in their collection) has six pieces and a block. The Smithsonian collections also include six pieces and a block.

content: This example of the model was exhibited at the Columbian Exposition, a World’s Fair held in Chicago in 1893.
