Let be a smooth irreducible projective algebraic curve defined over the complex numbers. The notion of the Clifford index of was extended a few years ago to semistable bundles of any rank. Recent work has been focused mainly on the rank- Clifford index, although interesting results have also been obtained for the case of rank . In this paper we extend this work, obtaining improved lower bounds for the rank- Clifford index. This allows the first computations of the rank- index in nontrivial cases and examples for which the rank- index is greater than the rank- index.
