We compute this torsion for vector bundles on quaternionic homogeneous spaces with respect to any isometry in the component of the identity, in terms of roots and Weyl groups.22 pages; requires Waldi's symbol font wasysym (included in teTeX)Differential GeometrySpectral Theory53C25; 58J52; 53C26; 53C35text
