We discuss a general strategy which produces an orthonormal set of vectors, stable under the action of a given set of unitary operators A j , j = 1, 2,. .. , n, starting from a fixed normalized vector in H and from a set of unitary operators. We discuss several examples of this procedure and, in particular, we show how a set of coherent-like vectors can be produced and in which condition over the lattice spacing this can be done.
