Description
This tan cut and glued paper model has sixty faces - twenty-four triangles, twenty-four quadrilaterals, and twelve irregular pentagons. The underlying structure is a pentagonal dodecahedron, whose faces are equal irregular penatgons. On each of these pentagons a figure is erected with two triangular, two quadrilateral, and one pentagonal face.
A tag on the model reads: 332. A mark in pencil reads: 3-24-34 (/) No. 332. Another mark in pencil reads: Symmetrical (/) Pentagonal (/) Dodecahedron (/) Second (/) Species. Another mark in pencil reads: Nonagonal (/) Dodecahedron.
Wheeler considered this to be the ninth in a series of models he called "Evolution of the Ppentagonal Dodecahedron." He also numbered it in his catalog D16 and called it a "Long Base Pentagonal Dodecahedron.".
