[17 F, 45 E, 30 V] This solid derives from another shape with twelve regular pentagons for faces. You take such a regular dodecahedron and split it into identical halves along a zig-zag path around its “equator.” Then pull them apart and twist one of the pieces a tenth of a turn around the axis along which you separated them. Bandage the two pieces back together with a ring of five hexagons, and you produce this elongated dodecahedron.
