The three spectra which we study are incomplete Room squares, uniform Room frames and Room frames of type $2^ut^1$.  These problems have been studied in numerous papers over the years; in this paper, we complete the three spectra.  In addition we find a Howell cube of type $H_3(6,10)$.  This corrects a previous claim of nonexistence of this design.<\/jats:p>","DOI":"10.37236\/346","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T23:13:18Z","timestamp":1578697998000},"source":"Crossref","is-referenced-by-count":6,"title":["The Spectra of Certain Classes of Room Frames: The Last Cases"],"prefix":"10.37236","volume":"17","author":[{"given":"Jeffrey H.","family":"Dinitz","sequence":"first","affiliation":[]},{"given":"Gregory S.","family":"Warrington","sequence":"additional","affiliation":[]}],"member":"23455","published-online":{"date-parts":[[2010,5,20]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v17i1r74\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v17i1r74\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T18:53:31Z","timestamp":1579287211000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v17i1r74"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,5,20]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2010,1,5]]}},"URL":"https:\/\/doi.org\/10.37236\/346","relation":{},"ISSN":["1077-8926"],"issn-type":[{"type":"electronic","value":"1077-8926"}],"subject":[],"published":{"date-parts":[[2010,5,20]]},"article-number":"R74"}}
