G&S GeoSite

I thought, as a diversion, that I would feature on this
web-site some of the geometric models that I
developed in 1976-1977. At the time, I called this
work "Base-9 Geometric Structure"; and the
structures themselves "Pentanon Spheres."

The five Pentanon Spheres, featured here, are
actually dodecahedral space enclosures; each and all
of which are built of identical sub-components.

All the graphics here are clips from my original
notebook; and are sketches of 3-D models of these
enclosures (which I have built). So, there are no fancy
computer graphics here.

Neither do I attach any particular significance to this
work. This is just for fun.

While we're at it, we may as well take a look at a
certain semi-regular polyhedron that I stumbled
across during this period (1976-77).

I call it a "Binary Icosahedron".

This may be a "new" polyhedron. That is, I have
not found it cataloged anywhere. If you are
aware of this polyhedron from some other
source, please let me know through the e-mail
address provided below. . .so that I might stand
corrected.

Actually, the chances of anyone coming up with a
"new" polyhedron, as simple as this one, these
days, are really quite remote. Nonetheless....
