In "Geodesic Math and How to Use It", Hugh Kenner writes, "Tables of chord factors, containing as they do the essential design information for spherical systems, were for many years guarded like military secrets. As late as 1966, some 3"ν" icosa figures from "Popular Science Monthly" were all anyone
