Seymour proved that 3-connected regular matroids are either graphs, cographs, or $R_{10}$, or else can be decomposed along a non-minimal exact 3-separation induced by $R_{12}$. Quasiregular matroids are binary matroids with no minor isomorphic to the self-dual binary matroid $E_4$. The class of quasiregular matroids properly contains the class of regular matroids. We prove that 3-connected quasiregular matroids are either graphs, cographs, or deletion-minors of $PG(3,2)$, $R_{17}$ or $M_{12}$ or else can be decomposed along a non-minimal exact 3-separation induced by $R_{12}$, $P_9$, or $P_9^*$.<\/jats:p>","DOI":"10.37236\/6911","type":"journal-article","created":{"date-parts":[[2020,1,10]],"date-time":"2020-01-10T15:16:28Z","timestamp":1578669388000},"source":"Crossref","is-referenced-by-count":1,"title":["Quasiregular Matroids"],"prefix":"10.37236","volume":"25","author":[{"given":"S.
