Several of the new three color bounds are derived from the two color constructions; specifically, we were able to use $(5,k)$-colorings to obtain new $(3,3,k)$-colorings, and $(7,k)$-colorings to obtain new $(3,4,k)$-colorings. Some of the other new constructions in the paper are derived from two well known colorings: the Paley coloring of $K_{101}$ and the cubic coloring of $K_{127}$.<\/jats:p>","DOI":"10.37236\/5254","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T18:27:34Z","timestamp":1578680854000},"source":"Crossref","is-referenced-by-count":2,"title":["New Lower Bounds for 28 Classical Ramsey Numbers"],"prefix":"10.37236","volume":"22","author":[{"given":"Geoffrey","family":"Exoo","sequence":"first","affiliation":[]},{"given":"Milos","family":"Tatarevic","sequence":"additional","affiliation":[]}],"member":"23455","published-online":{"date-parts":[[2015,7,17]]},"container-title":["The Electronic Journal of Combinatorics"],"original-title":[],"link":[{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v22i3p11\/pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v22i3p11\/data","content-type":"application\/zip","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/download\/v22i3p11\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,1,17]],"date-time":"2020-01-17T05:14:08Z","timestamp":1579238048000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.combinatorics.org\/ojs\/index.php\/eljc\/article\/view\/v22i3p11"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015,7,17]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2015,7,1]]}},"URL":"https:\/\/doi.org\/10.37236\/5254","relation":{},"ISSN":["1077-8926"],"issn-type":[{"value":"1077-8926","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015,7,17]]},"article-number":"P3.11"}}
