    Die Wurzeln der Gleichung \(u^2+v^2+w^2=0\) sind 3 complexe Zahlen, welche als Endpuncte der Projectionen dreier zusammenstossender Würfelkanten dargestellt werden. Die Wurzeln der Gleichung \(u^2+v^2=0\) sind 2 complexe Zahlen \(\pm(x_1+iy_1)\) und \(\pm(x_{11}+iy_{11})\); \(x_1\) und \(y_1\) sind die Coordinaten eines beliebig gewählten Punctes und \(x_{11}\) und \(y_{11}\) sind die Coordinaten des Durchschnittspunctes zweier gleichseitigen Hyperbeln, welche zu den beiden durch den Punct \(x_1 \;y_1\) gehenden Hyperbeln correspondirend sind.
