In what way are the vertices not orthogonal? BrianCo 23:51, 21 May 2007 (EDT)
- You got me. Can't a vertex not be orthogonal? I was relatively weak in the 3-dimensional stuff.--Aschlafly 23:55, 21 May 2007 (EDT)
- A vertex may be not-orthogonal but in a cube they are. For some reason Rschlafly removed orthogonal. BrianCo 00:25, 22 May 2007 (EDT)
