I hope this is not too trivial for this forum. I was wondering if someone has come across this polytope. You start with the [rhombic dodecahedron][1], subdivide it into four parallellepipeds, [![enter image description here][3]][3] and then fill the space between the four parallellepipeds with a tetrahedron, six parallellepipeds and four prisms (hopefully i counted correctly), so as to obtain a convex polytope. Does this have a name? could someone provide a link to a picture?
