[Domesteading 00303] vertex arrangement

[Dick Fischbeck]

Hi Sal

Any geometrically permissible arrangement of vertexes is possible. It
could be tetrahedral, octahedral, what ever one wants.  Every
polyhedron can be constructed with vertex elements. 

The largest RanDome is in East Belfast, Maine.  It is 8.5 m in
diameter. It is a membrane structure of 0.040 aluminum. It's been
through 4 winters now.

I did notice in one photo in Dick's web pages that the vertexes in a
 metal randome had a decidedly hexagonal-looking arrangement.
This is course opens the possibility to discuss things like virtual or
 implied vertexes, composite struts etc.  The hexpent domes, while
being
 composed of flat faces, have implied struts that are just not
 connected.
