The 16 vertices of a 4-cube [Les 16 sommets d'un hyper-cube à 4 dimensions].




Let E be a N-dimensional space. It contains a set S of points {P(i)} with coordinates {C(1),C(2),...,C(N)}. The set S is visualized using a tridimensional euclidian space {OX,OY,OZ}:

Next figure displays a tridimensional (N=3) point (with coordinates {C(1),C(2),C(3)}) as a triangle:
