>I meant "face", not "side". Okay but if you're going to ground your position in "hey, this is just what you get when you're super rigorous about terms and assumptions and all", it's incumbent on you to be a little more careful about that. >However, almost all the solutions to make this a possible polyhedron make it not a pyramid and operate under the assumption that there is hidden information (that is, that the image is misleading, deliberate or not). It still remains an impossible pyramid in Huffman's context. And again, that's adding information that is not present in the image itself, the exact problem you claimed would invalidate the offered solution (in this subthread), and it's still a different definition of "impossible figure" than the conventional one.
