Berman, Martin
Description
This model has a regular decagon on the bottom and a regular pentagon on the top. Above the decagon are twenty triangles. Above the triangles are five pentagons alternating with five sets of two triangles. This comes to a total of thirty equilateral triangles, six regular pentagons, and one regular decagon.
On Berman's models of regular-faced convex polyhedra, see 1978.1065.01.
