RBF Definitions
"It is a characteristic of the icosahedron’s great circles
59° 02’
54° 54’
54° 54’
168° 50’ to make symmetrical interception of themselves.
"In maintaining triangular grids of this surface, an altitude
will continue as an edgeand the exterior triangulation, with
the exception of the 180 circles which ‘quantum’ the 20
icosahedral triangular apexes will have yes-n-yes-no and the
set can be made continuous one way or the other, but not both
at the same time."
