Hi,
as far as I could tell the function truncated_cuboctahedron() really constructs a truncated octahedron (instead of a truncated cuboctahedron of course).
Best regards

Thanks!

Hi, I would like to compute all lattice points of a polytope via the callable library, e.g. Main pm; pm.set_application("polytope"); perl::Object p("Polytope<Rational>"); p.take("VERTICES") << (ones_vector<Rational>() | 5*unit_matrix<Rational>(4)); Matrix<Rational> latp...

No question here, just trying to safe some time of someone having similar issues. I just installed polymake on Mac OS 10.9 via Fink and had some (small) issues. I did everything as described in http://polymake.org/doku.php/howto/mac_compiling_fink , but running 'make' I got the error Unable to find ...

I think I got it:
Using perl::Object p("Polytope<Rational>"); instead of perl::Object p("Polytope<Float>"); eliminates all errors. Why is that? Must I always use Polytope<Rational>?

Ah, I didn't knew that. And yes, both 'DIM' and 'AMBIENT_DIM' are equal to 3 (if that's helpful).

Hi Andreas, having a not full-dimensional polytope was my initial thought. However, I tested this with polytopes which are guaranteed to be full dimensional (e.g. cube). Interestingly, polymake tells me that FULL_DIM is true and CONE_DIM as well as CONE_AMBIENT_DIM is 4 (I'm working with 3 dimension...

Hi, when I try to determine the volume of a polytope running the following code: perl::Object K; [...] Rational vol=K.give("VOLUME"); polymake throws an exception: polymake: WARNING: could not compute 'VOLUME' probably because of unsatisfied preconditions: precondition : CONE_DIM, CONE_AMB...

Thanks. Yes, I'm always using nodes_of_dim, just quickly took the example from your tutorials. Nice to know nonetheless.

Hi,
can I assume that the facets given by (for sake of simplicity let us consider only a 3-dimensional polytope)
Are in the same order as ?
