34. (Formula presented)(Formula presented) is not the special value because Ryan and Shepley in Ref. 13, use an off-diagonal parametrization for (Formula presented) in Bianchi VI(Formula presented); (Formula presented)(Formula presented) is obtained as special value if one chooses the diagonal parametrization.

37. (Formula presented) is a parameter with value I, II, (Formula presented), IX denoting the Bianchi classification, (Formula presented) stands for diagonal, and an arrow indicates the orientation of (Formula presented). Hence, in a (Formula presented) model, (Formula presented) has only a timelike component, in a (Formula presented) model only spatial components, while in a (Formula presented) model both components appear.
