Index Entry
The projective transformation “consists of great circle bounded triangles of any angular magnitude which can transform the comprehensive geographical data of the world from spherical to planar by employment of either the spherical tetrahedron, spherical cube, spherical octahedron, or spherical vector equilibrium and its alternate, the icosahedron, of any development of these. . . It is a discovery of synergetics that there are no other spherical triangular grid bases other than the above.”
