My friend Gianni Sarcone recently built a 12 prism construction.

So I had to build one myself. I also built in in Mathematica. To my surprise, I was able to simplify it down to three points.

base={{4,4,7},{3,6,6},{2,5,8}}; prismp=Join[base,-(Reverse/@base)]; prismf={{1,2,3},{4,5,6},{1,2,4,5},{1,3,6,5},{2,3,6,4}}; tetrahedralGroup ={{{-1,0,0},{0,-1,0},{0,0,1}},{{0,-1,0},{0,0,1},{-1,0,0}},{{0,0,1},{-1,0,0},{0,-1,0}},{{0,0,-1},{1,0,0},{0,-1,0}},{{0,1,0},{0,0,-1},{-1,0,0}},{{1,0,0},{0,1,0},{0,0,1}},{{0,-1,0},{0,0,-1},{1,0,0}},{{-1,0,0},{0,1,0},{0,0,-1}},{{0,0,1},{1,0,0},{0,1,0}},{{1,0,0},{0,-1,0},{0,0,-1}},{{0,0,-1},{-1,0,0},{0,1,0}},{{0,1,0},{0,0,1},{1,0,0}}}; Graphics3D[{Opacity[.8],Table[Polygon[prismp[[#]].tetrahedralGroup[[n]]]&/@prismf,{n,1,12}]}, Boxed-> False, SphericalRegion->True,ImageSize-> {800,800},ViewAngle-> Pi/9]

Maybe try out ViewAngle -> Pi/600, ViewPoint -> {200, 0, 0}

Sweet.
