Re: Perles Irrational Polytope (in polymake)

I see, thanks.

Also, is it possible to compute the convex hull of irrational vectors (say with coordinates in a quadratic extension), and then compute the facets of the resulting polytope?

Perles Irrational Polytope (in polymake)

Hello, I have the following naive question. The vertices of perles 8-dimensional irrational polytope are expressed in terms of the square root of 5, denoted r5. For example one coordinate of one vertex is " -1/2 + 1/2r5". I am not fully certain whether this expression is -1/2 + (1/2)r5 or -1/2 + 1/(...

Computing the coordinates of the Vertices_in_facets ?

Hello, I am quite new to both polymake and programming and my question is this: I have a 6 dimensional polytope with 48 vertices, and I am interested in computing the vertices that are contained in each facet. I was able to use the VERTICES_IN_FACETS command which is great, however I would love to h...

affine dependencies of a polytope

Hello, I am new to polymake, and computing in general, so I apologize if this is an easy fix. I am trying to compute the affine dependencies of a polytope P=conv(x1,..,x_n). So by this I mean identifying the maximal affinely independent subset of the vertex set {x_1,...,x_n}, and then expressing the...
