| #### D.13.2.22 gorensteinVector Procedure from library `polymake.lib` (see polymake_lib). Usage: gorensteinVector(p); p polytope Assume: isGorenstein(p)==1 Return: intvec, a vector v such that n*p+v is reflexive for some factor n Note: the factor n can be computed via gorensteinIndex(p) Example:
    LIB "polymake.lib";
