Suppose we have a tournament with edges labelled so that the edges incident with any vertex have at most k distinct labels (and no vertex has outdegree 0). Let m be the minimal size of a subset of labels such that for any vertex there exists an outgoing edge labelled by one of the labels in the subs

Let &a be a plane lattice and {vl, v2} a Minkowski reduced base of ~. In this note we prove that ifa convex body X has minimal width w(X')/> Iv2[ sin ~p + Ivll(x/3/2), where ~o is the acute angle between vl and v2, then X" is a covering set for ~.
