Hi Peter,

As I mentioned on the Mathematica Users Forum, the general problem isn't well-defined: that's to say, given an ordered list of vertices, it's not in general possible to deduce what polyhedron this list is meant to specify.

The tetrahedron problem *is* well-defined. I don't think there's an inbuilt Mathematica function that does that (though I may be wrong), but it wouldn't be that hard to write your own. On the forum, I've posted a function I've called 

  tetrahedronByVertices

that does tetrahedra in this way.
