D.W. Hall proved that every simple 3-connected graph with a Ks-minor must have a K3.3-minor, the only exception being Ks itself. In this paper, we prove that every 3-connected binary matroid with an M(Ks)-minor must have an M(K3.3)-or M\*(K3,3)-minor, the only exceptions being M(K5), a highly symmet

Let A be an m\_n matrix in which the entries of each row are all distinct. A. A. Drisko (1998, J. Combin. Theory Ser. A 84, 181 195) showed that if m 2n&1, then A has a transversal: a set of n distinct entries with no two in the same row or column. We generalize this to matrices with entries in the
