If the automorphism group of a maniplex M partitions the vertex-set of M into k distinct orbits, we say that M is a k-orbit n-maniplex. The symmetry type graph of M is the quotient pregraph obtained by contracting every orbit into a single vertex. Symmetry type graphs of maniplexes satisfy a series of very specific properties. The question arises whether any pregraph of order k satisfying these properties is the symmetry type graph of some k-orbit maniplex. We answer the question when k = 2.", "revisions": [ { "version": "v1", "updated": "2018-12-10T23:34:18.000Z" } ], "analyses": { "keywords": [ "symmetry type graph", "two-orbit maniplexes", "existence result", "generalises abstract polytopes", "specific properties" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
