Product Description
This model represents the images of the 15 great circles representing the reflection hyperplanes of the icosahedral group under the map (x,y,z)->(yz,xz,xy).  The image of the unit sphere under this map is Jakob Steiner's so-called "Roman" surface, and the image of any circle under this map is an ellipse on this surface.  Thus, one should be able to identify a total of 15 distinct tori, each representing an ellipse on this surface.
