This beautiful model to cut out and glue together has sixty spikes, each with three faces, making 180 faces in all. It is coloured in twenty different colours each of which defines a plane surface and which is represented by nine faces. Looked at another way it has twelve clusters of five spikes showing the relationship with the dodecahedron.

The book contains everything you need to make the model, excepting cutting and glueing materials. With a little patience a wonderful model emerges!
