Parameter depends upon ratios of physical parameters: and
does not depend upon the quasi–Cartan matrix and, hence, upon intersections
of The parameter depends upon ratios
where are functions of GM, and The calculation of

(54) coincide with those obtained in [7] for block–orthogonal case, when
charges are coinciding inside blocks. For most interesting
solutions with and (53)
