I guess.  I read it in some book from Buckminster Fuller when I was
looking for info on calculating geodesics.  I had to come up with my own
method.  I guess the only place he puts the actual calculations is in
his patents.  I tried to get a copy of his geodesic dome patent from the
patent trademark office web site, but it didn't seem to work.  The way
my dome was calculated it looks ok, but I know that it isn't the
standard method.  All of the struts along an edge of a icosahedron
triangle are the same length in my design.  In no listing of lengths I
have found on the web is this true.  When I find out how Buckminster did
it maybe I will make new versions of my geodesic functions.
