Indicates whether an input list should be treated as the vertices of a polytope, the ground set of a matroid or the facets of an abstract polytope.
Further information
Default value: polytope
Function: getFacetBases -- given a slack matrix or a list of vertices of d-polytope or a rank d+1 matroid, or (d+1)-cone generators, creates a sorted list of vertices (empty if a matrix is given as input) in the order corresponding to B, and B the list of d spanning elements for each facet
Option name: Object -- select the combinatorial object which the input should be interpreted as
