text: FIG.10 - Five-coloured icosahedron generated by the intersection of as many tetrahedra, whose faces are orthogonal to all the 3-fold axes present in the icosahedron.
text: With reference to the five sets of three orthogonal 2-fold axes previously described, the rhombic triacontahedron may be regarded as deriving from the intersection of five cubes; the faces of each cube are orthogonal to one of the five sets of three 2-fold axes.
