I realize you are trying to keep it concise, but I have 2 suggestions for geometry and interfaces:
geometry: p = polytopes.twenty_four_cell() show(p.render_wireframe(), frame = False) and interfaces (Gfan): r3.<x,y,z> = PolynomialRing(QQ,3) vort_ideal = r3.ideal([-6*x*y*z+x*y+x*z+6*y*z-y^2-z^2, -6*x*y*z+x*y+y*z +6*x*z-x^2-z^2, -6*x*y*z+z*y+x*z+6*y*x-y^2-x^2]) show(vort_ideal.groebner_fan().render(), axes = False, figsize= [4,4*3.0^(1/2)/2]) Just my own biases... -Marshall On Jun 5, 7:04 pm, William Stein <wst...@gmail.com> wrote: > 2009/6/5 kcrisman <kcris...@gmail.com>: > > > > >> due to a *major* bug in the tinyMCE integration, which anybody who has > >> seriously used the SAge notebook has run into.
