Trigonal trapezohedron? edit
As best I can tell, the rhombohedron and trigonal trapezohedron should be identical. All edges are equal length, but hard to see how the acute angles can be different. The MathWorld link is the source of this claim. Tom Ruen (talk) 05:16, 28 June 2011 (UTC)
Rhombohedral symmetry? edit
This removed gallery doesn't seem to reflect this polyhedron, even if they have rhombohedral symmetry! Tom Ruen (talk) 05:39, 28 June 2011 (UTC)
- Rhombisches Prisma.svg (#4) looks like a right rhombic prism, doesn't it? 8-)
- Oops! No: its vertical faces are rectangles but not squares, so not rhombi... :-P
