A key ingredient is a new theoretical result (akin to a theorem by Neumann-Zagier and Moser for ideal triangulations upon which HIKMOT is based) showing that there is a redundancy among the edge equations if the edges avoid \"gimbal lock\". We successfully test the algorithm on known examples such as the orientable closed manifolds in the Hodgson-Weeks census and the bundle census by Bell. We also tackle a previously unsolved problem and determine all knots and links with up to 14 crossings that have a hyperbolic branched double cover.", "revisions": [ { "version": "v1", "updated": "2019-04-27T02:55:33.000Z" } ], "analyses": { "subjects": [ "57M50", "65G40" ], "keywords": [ "verified computations", "closed hyperbolic", "interval arithmetic methods", "extending methods first", "bundle census" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable" } } }
