We show that these all have dimension 2^m. Using this, we are able to realize W_q(m) as the space of invariants of a reprsentation of the Hecke algebra H_m. We also give a conjecture in the general case.To appear in the Proceedings of the LMS symposium on Quantum Groups, Durham, EnglandQuantum Algebratext
