Veit, Thanks for explaining what the cross section was for. Jim, look at a the cut-away dodec. on the left of <
http://gosper.org/dodex.gif>. There’s a special plane orthogonal to the 3-fold axis where the cross-sections are regular hexagons. You need to check that when extended above and below this plane the dodec’s don’t interpenetrate, but it seems to me that part of the construction also holds water.
:-) Jim
