The 'hyperbolic cosine' of a sphere [Le 'cosinus hyperbolique' d'une sphère ]

The 'hyperbolic cosine' of a sphere [Le 'cosinus hyperbolique' d'une sphère].




A tridimensional object is defined as a set of points P={X,Y,Z}. To each point P is associated the following pseudo-octonion O={X,Y,Z,0,0,0,0,0}. Then each pseudo-octonion O is submitted to the transformation: 
                    
                    O --> O' = cosh(O)


At last a new point P' is defined with {X',Y',Z'} being arbitrary linear combinations of the components of O'. The set of points P' defines a new tridimensional object...
