Bill Gosper, Another example, where all faces are identical, is the endo-dodecahedron. (The Symmetries of Things, p. 328) Which maths camp was this? Was Julian at IMO 2011, also? Sincerely, Adam P. Goucher
Julian flew back from math camp today (on one hr's sleep) and, generalizing a question of mine, found a dodecahedron with (planar) equilateral pentagonal faces, but not the usual ones. Before peeking <http://gosper.org/dodohedron.png>, you might try to find one. After peeking, please speak up if you've seen it before.
