Abstract
We show how to construct a complete set of eigenstates of the hamiltonian of the one-dimensional Hubbard model on a lattice of even length . This is done by using the nested Bethe Ansatz {\it and} the symmetry of the model. We discuss in detail how the counting of independent eigenstates is carried out.
