Permute the triple , , in all six possible ways and form the six corresponding inequalities , , etc. Plot these relations in 3D with to split the unit cube into six congruent right-angled tetrahedra (called "orthoschemes").


In 2D there are two right-angled triangles, corresponding to and ; in 4D there are 24 simplices corresponding to , etc.
