Thanks. I'm Xah's friend :-) The Lojban dictionary I have lists "kubli" as being a regular polyhedron --- is this correct? If it is, I'm not sure what the "nic" signfies in "vonynickubli". Does "kubli" imply convexity, or some other property beyond regularity? If not, there are 4 candidates for the 12-sided regular polyhedron. "Regular polyhedron" in modern use doesn't typically imply convexity. (There are 9 regular polyhedra, 5 of which are convex.) Comments? Why is "vonkubli" preferable to "kubli fi vo"?
