: We construct a quadratic basis of generators of matrix-extended W 1+ 1 using a generalization of the Miura transformation. This makes it possible to conjecture a closed-form formula for the operator product expansions de(cid:12)ning the algebra. We study truncations of the algebra. An explicit calculation at low levels shows that these are parametrized in a way consistent with the gluing description of the algebra. It is perhaps surprising that in spite of the fact that the algebras are rather complicated and non-linear, the structure of their truncations follows very simple gluing rules
