This is a significant extension of the notion of crown for isomorphic chief factors.2022http://zaguan.unizar.es/record/11248410.1007/s13398-021-01188-zhttp://zaguan.unizar.es/record/112484oai:zaguan.unizar.es:112484info:eu-repo/grantAgreement/ES/DGA/E22-20Rinfo:eu-repo/grantAgreement/ES/MCIU-AEI/PGC2018-095140-B-I00Revista de la Real Academia de Ciencias Exactas, Fisicas y Naturales - Serie A: Matematicas 116, 1 (2022), [7 pp.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
