a friend wanted to know how to say "great dodecahedron" in lojban.

So, how does one say the five regular solids?

tetrahedron
cube/hexahedron
octahedron
dodecahedron
icosahedron

and then, the various variations: truncated, stellated ... etc. Is there a systematic treatment somewhere?

thanks.

here's the message my friend wrote:

I'm looking for the Lojban for "great dodecahedron". Any ideas? I don't know much about Lojban, but I've managed to piece together the following, possibly incorrect / inelegant constructions:

tetrahedron - kubli fi vo
cube - kubli
octahedron - kubli fi bi
dodecahedron - kubli fi pare
icosahedron - kubli fi reno

These constructions seem simpler than "kubli ci boi ..." and "kubli zo'e ...". Perhaps there is something even simpler?

Of course, keeping up this approach produces ambiguous names / descriptions of the remaining four regular polyhedra.

Any comments? Any ideas on who else might have ideas? Two possibilities I've thought of that won't help: (in the 3d case) adding sumti for lower-dimensional totals (faces, then edges, then vertices) and adding a sumti for # of faces around an edge. Should additional words be used to describe the shape? Should a new word be introduced for describing polyhedra in more detail? (e.g. based on Wythoff symbol)
