  | #### D.16.2.38 vertexEdgeGraph `Syntax:` `Polymake::vertexEdgeGraph(` polytope p `)` `Type:` list `Purpose:` the first entry is a bigintmat containing all vertices as row vectors, and therefore assigning all vertices an integer. the second entry is a list of intvecs representing the edge graph of the vertices of p, each intvec represents an edge of p connecting vertex i with vertex j. `Example:`
