These pages are to give flight to your imagination. The 31 great circles of the icosahedron are the equators of the axes of spin of opposite pairs of features. There are:
- 15 axes of the 30 edges (green)
- 6 axes of the 12 vertexes (red)
- 10 axes of the 20 faces (blue)
Above is a QTVR model of the interior of this figure.
