P=Polyhedron(vertices=[[0, 1, 0, 4] , [0, 1, 1, 3] , [3, 1, 1, 0] , [3, 1, 0, 1] , [0, 3, 0, 2] , [0, 3, 1, 1] , [1, 0, 0, 4] , [1, 0, 1, 3] , [3, 0, 1, 1] , [3, 0, 0, 2] , [1, 3, 1, 0] , [1, 3, 0, 1]])
P.plot()
This is a polytope living in R^4, but in fact the sum of the coordinates of each vertex is 5, so it is a 3D polytope. In some cases, sage gives me a nice 3D view of how the polytope looks like, but in this case it gives me something that doesn't even looks convex, so it is not the right projection. I would like to know what is going on and try to solve this issue, so I appreciate ideas on how to correct this, and where to look at on the code.

I tried:
icosahedron()
and worked perfectly, but then I tried
v=[(0,0,0),(0,1,0),(0,2,1),(1,0,0),(1,2,3),(2,1,1)]
Polyhedron(vertices=v).plot()
and I only get a single bullet, no error message, no image, no nothing... What is going on?EmersonLWed, 29 Oct 2014 17:57:17 +0100https://ask.sagemath.org/question/24686/
