On the special normal surfaces of the 5-dimensional projective space. (Russian. English, German summaries) Zbl 0606.51018

Using the stereographic projection in 4-dimensional projective space of the special normal surface \(F^ 4_ 2\) of the 5-dimensional projective space \(P_ 5\), some results on the position of the elements of \(P_ 5\) with respect to \(F^ 4_ 2\) are obtained. A Cremona transformation of 4-th degree between two hyperplanes of \(P_ 5\) is obtained by the bisecants of \(F^ 4_ 2\).
