Reporter: mhampton | Owner: mhampton

------------------------+---------------------------------------------------
The following causes cddlib to crash; I'm not sure if this is fixable
without patching the cddlib source:
{{{
p4 = polytopes.permutahedron(5,project=True)
pn4 = p4.projection()
p3 = pn4.schlegel()
verts = p3.transformed_coords
edges = p3.lines
topes = []
for q in p4.facial_incidences():
topes.append([verts[i] for i in q[1]])
Polyhedron(vertices=topes[3], field=RDF, verbose=True)
}}}
output ends with:
{{{
Facet graph
*Error: Possibly an LP cycling occurs. Use the Criss-Cross method.
}}}
