....separated in polynomial time, unless P = NP. Interesting open questions include: What is the computational complexity of separating inequalities arising from generalized antiwebs Do other PFS specific rank facets exist Does the polytope PFS admit higher order facets besides the ones studied in [9] with 0, 1, 2 coefficients Acknowledgements. The authors would like to thank Michael Joswig, Volker Kaibel and Gunter M. Ziegler for helpful discussions. We are also grateful to the anonymous referees for useful comments that improved the paper. Appendix To prove Lemma 3 of Section 3.1, we ....
