Spherical Octahedron:
“Each of any three great circles of a sphere not having common polar crossings must cross each other twice in a symmetrical manner in which the six crossings must produce either two similar polar triangles and six similar equatorial triangles, or must produce eight equilateral and equiangular triangles all cases of which are spherical octahedra, regular or irregular.”
