The vertex-first parallel projection of the tesseract into three-dimensional space has a rhombic dodecahedral envelope. What is the four-dimensional projection of the five-cube? By analogy, its envelope should be a four-dimensional polytope that dissects into 5 congruent "rhombic" tesseracts in two possible ways. What's the name of this object?
