    Durch eine geeignete Definition des kubischen Strahlenkomplexes wird jedem seiner Strahlen ein Punkt auf diesem zugeordent. Konjugierten Strahlenpaaren entsprechen Punktepaare einer allgemeinen kubischen involutorischen Transformation. Der kubischen Schnittkongruenz des Ausgangskomplexes mit einem kinearen Komplex ist eine Fläche \(F_4\) der kubischen Schnittregelschar des Ausgangskomplexes mit zwei linearen Komplexen eine näher untersuchte Kurve \(C_7\) zugeordnet. - Mit gleichartigen Methoden werden der quadratische Komplex und seine \textit{Cremona}schen Transformationen untersucht.
