We develop tools based on cohomology and linear algebra that either lend themselves to direct count of the isomorphism classes (notably in the case of nilpotent loops of order $2q$, $q$ a prime), or lead to efficient classification computer programs. This allows us to enumerate all nilpotent loops of order less than $24$.", "revisions": [ { "version": "v1", "updated": "2015-09-18T17:24:59.000Z" } ], "analyses": { "subjects": [ "20N05", "20J05", "05B15" ], "keywords": [ "cohomology", "enumeration", "efficient classification computer programs", "direct count", "centrally nilpotent loops" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150905713D" } } }
