We study these matrices in this article. Using these matrices, we give some recipes to construct solutions, which include the multipermutation level $2$ solutions. As an application of these, we construct a multi-permutation solution of level $r$ for all $r\\geq 1$. Our method gives alternate proof that the class of permutation groups of solutions contains all finite abelian groups.", "revisions": [ { "version": "v1", "updated": "2023-03-15T09:54:51.000Z" } ], "analyses": { "keywords": [ "quantum yang-baxter equation", "cycle matrix", "combinatorial approach", "set-theoretic solutions", "finite abelian groups" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
