Again for a particular curvature restriction on $R$ and the Ricci tensor $S$ there arise two structures, e. g., local symmetry ($\\nabla R = 0$) and Ricci symmetry ($\\nabla S = 0$); semisymmetry($R\\cdot R =0$) and Ricci semisymmetry ($R\\cdot S =0$) etc. In differential geometry there is a very natural question about the equivalency of these two structures.
