Meanings

A Catalan solid with 60 isosceles triangle faces, 90 edges and 32 vertices, being the dual of the truncated dodecahedron.
For example, with no hint of justification, it is stated (page 118) that "the icosahedron contains as much interior volume relative to surface area as is possible with only one type of face"; in fact, the triakis icosahedron does noticeably better in that respect.
