The constructions are based on choosing cosets of the unit group of a subring in the Galois ring $\\mathrm{GR}(p^2,p^{2s})$. Two infinite families of disjoint difference families are obtained from the Galois rings $\\mathrm{GR}(p^{2},p^{4n})$ and $\\mathrm{GR}(2^2,2^{2s})$.<\/jats:p>","DOI":"10.37236\/6006","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T10:50:32Z","timestamp":1578653432000},"source":"Crossref","is-referenced-by-count":3,"title":["Disjoint Difference Families from Galois Rings"],"prefix":"10.37236","volume":"24","author":[{"given":"Koji","family":"Momihara","sequence":"first","affiliation":[]}],"member":"23455","published-online":{"date-parts":[[2017,8,11]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v24i3p23\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v24i3p23\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,16]],"date-time":"2020-01-16T23:50:29Z","timestamp":1579218629000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v24i3p23"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,8,11]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2017,7,14]]}},"URL":"https:\/\/doi.org\/10.37236\/6006","relation":{},"ISSN":["1077-8926"],"issn-type":[{"type":"electronic","value":"1077-8926"}],"subject":[],"published":{"date-parts":[[2017,8,11]]},"article-number":"P3.23"}}
