[lojban] prism

[Pierre Abbat <phma@bezitopo.org>]

On Skype I mentioned that I need a helper to hold the prism pole. I called the 
prism "cibminra"; would "kubminra" be better?

A mathematical prism is a shape consisting of two congruent ends in different 
parallel planes, connected by sides which are all parallel to some line. An 
optical prism is a transparent device with flat sides, not all of which are 
parallel. Some optical prisms are mathematical prisms, such as the equilateral 
triangle prism used to split a beam into colors, but some aren't. The prism in 
the prism pole doesn't even have all sides flat. It's a circular cylinder with 
three mutually perpendicular flat faces on the inside end and one flat face on 
the outside end.

So should we have more than one word for "prism"? What should they be?
