In recent papers [1-3], we have discussed matter symmetries of non-staticspherically symmetric spacetimes, static plane symmetric spacetimes andcylindrically symmetric static spacetimes. These have been classified for bothcases when the energy-momentum tensor is non-degenerate and also when it isdegenerate. Here we add up some consequences and the missing references aboutthe Ricci tensor.Comment: 7 pages, no figure, LaTe
