The Lunar-holed Rhombicosidodecahedron, Stewart's E5/6J91(P4). This is a Rhombicosidodecahedron (called E5 by Johnson), with a 6-way hole through it made from Stewart's 6J91(P4), as described on pages 128-129 of Stewart's book (2nd ed.). Stewart writes It is unusual becuse each of the six openings is a lunar complex, rather than a single face, giving to the tunnels a novel, slit-like appearance. By "lunar complex", Stewart is referring to a "lune", which Johnson defines to be: Image:Lune.jpg

WARNING: The pentagons only barely almost-fit in the outer shell of this model. That's because you can't comfortably fit a Geomag pentagon panel into the base of a pentagonal pyramid -- the angles are too extreme. For the pictures I took, I only put in the 4 visible pentagons, and then didn't breathe too heavily as I took the pictures, lest they pop out. If you look carefully at the pictures, you may be able to see that the pentagons stick out more than they should.
