In this paper, we continue studying the 6-dimensional pseudo-Riemannian space V^6(g_{ij}) with signature [++--], which admits projective motions, i. e. continuous transformation groups preserving geodesics. In particular, we determine a necessary and sufficient condition that the 6-dimensional rigid h-spaces have constant curvature., Comment: 10 pages, LaTeX

In this note we find a 6-dimensional h-spaces of the $[(21...1)(21...1)...(1...1)]$ type and then determine quadratic first integrals of the geodesic equations of these h-spaces., Comment: 9 pages, LaTeX

In this note we find the metric of 6-dimensional h-space of the [33] type and then determine an important projective group characteristic of this h-space., Comment: 8 pages, LaTeX (corrected misprints)
