For any faithful representation V of a non-trivial p-group over a field of characteristic p > 0, it is known that the ring of vector invariants of m copies of V is not Cohen-Macaulay if m 3. However, much less is known about the case m = 2. In this paper we show that, if m = 2 and the group is an Ab
