ces has six facets.

<p>If you use '<a href="qh-optq.htm#Qt">Qt</a>' (triangulated output),
all facets will be simplicial (e.g., triangles in 2-d).  For the cube
example, it will have 12 facets.  Some facets may be
degenerate and have zero area.

<p>If you use '<a href="qh-optq.htm#QJn">QJ</a>' (joggled input),
all facets will be simplicial.  The corresponding vertices will be
slightly perturbed.  Joggled input is less accurate that triangulated
output.See <a
