Talk:Desmic system


 * related like the two tetrahedra inscribed in a cube.

I don't understand this phrase at all. I can imagine many tetrahedra inscribed in a cube. Two of them could overlap or be bounded away from each other, and more generally, many different sorts of relationships could exist between two of them. Michael Hardy (talk) 03:54, 3 July 2009 (UTC)


 * The figure and the description "like the two tetrahedra inscribed in a cube" are hopelessly inadequate
 * a pair of desmic tetrahedra are such that each edge of one intersects a pair of opposite edges of the other (see, eg., J A Todd, Projective and Analytic Geometry, Pitman 1947 - et cetera)Ericlord (talk) 09:14, 31 October 2009 (UTC)
