An (n,k)q-MDS code C over an alphabet $\cal A$ (of size q) is a collection of qk n---tuples over $\cal A$ such that no two words of C agree in as many as k coordinate positions. It follows that n 驴 q+k驴1. By elementary combinatorial means we show that every (6,3)4-MDS code, linear or not, turns out to be a linear (6,3)4-MDS code or else a code equivalent to a linear code with these parameters. It follows that every (5,3)4-MDS code over $\cal A$ must also be equivalent to linear.
