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.
