We describe a set of operations on book representations that preserves ambient isotopy, and apply these operations to $K_6$, the complete graph with six vertices. We prove there are exactly 59 distinct book representations for $K_6$, and we identify the number and type of knotted and linked cycles in each representation. We show that book representations of $K_6$ contain between one and seven links, and up to nine knotted cycles. Furthermore, all links and cycles in a book representation of $K_6$ have crossing number at most four.", "revisions": [ { "version": "v1", "updated": "2017-03-24T01:49:53.000Z" } ], "analyses": { "subjects": [ "57M15", "05C10", "57M25" ], "keywords": [ "classification", "preserves ambient isotopy", "distinct book representations", "operations", "dimensional space" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
