This graph is a DDG with parameters (4n, n+ 2, n − 2, 2, 4, n). In the paper we consider DDGs with these parameters. We prove that if n is odd then such graph can only be a 4 × n-lattice graph. If n is even we characterise all DDGs with such parameters. Moreover, we characterise all DDGs with parameters (4n, 3n − 2, 3n − 6, 2n − 2, 4, n) which are related to 4 × n-lattice graphs.","PeriodicalId":45858,"journal":{"name":"Siberian Electronic Mathematical Reports-Sibirskie Elektronnye Matematicheskie Izvestiya","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42044226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
