Šarac, Marica Octahedral noncompact hyperbolic space forms with finite volume. (English) Zbl 0891.53008 Mat. Vesn. 49, No. 1, 69-76 (1997). By pairing faces, via isometries from two groups which act discontinuously and freely on the hyperbolic three-space, of the same regular octahedron with all ideal vertices whose faces form angles \(\pi/2\), the author constructs two new nonorientable, noncompact hyperbolic space forms. These two space forms appear to be isometric.
