| * Wrong meridian. A Cahill-style map, unlike
here, divides at 20º W, so as not to split Africa, Spain, UK, etc..
On this map, no other layouts (N. Pacific or S. Atlantic, etc.) are possible
without splitting continents. Original caption: Conformal Octahedron; Polyhedral Globe; Platonic Solid; Source: John Parr Snyder’s Personal Software |
