Yep, polytopes.blah().show(), is fine although I do not like the default green as much (It was chosen to differentiate it from the lines and vertices, I assume). Yes, I think this is as good or better. Should we put a ticket to simply make the regular solid calls go to polytope.blah.show(). I'm not sure how else they are being used.
I also wonder if the vertex bug is hiding in these as well? Now, for the reason I encountered the bug...I was goofing around (I needed a break from reviewing proposals) trying to make my 3-D version of the logo (a few years back :) ) adaptable. It looks like most of what I want is available here. The problem is I never would have found them without the above pointers. ASIDE: if you start with "geometry." or "sage.geometry." and start working through tab completion I am not sure you would ever get to the construction polytopes.blah().show() for the regular solids. You don't get to the regular solids until "sage.geometry.polyhedron.library.Polytopes.blah(). Why would I guess that I can shorten the call to "polytopes.blah().show()? Why does polytopes (part of geometry) show up as a root level class? I'm beginning to think a committee needs to be tasked with restructuring the class hierarchy so that things can be found. Sagemath is actually quite wonderful, but it can be hard to find what you want.
