We give a complete set of orthogonal invariants for tetrahedra in G 2(R8). As a consequence, we characterise regular tetrahedra and we exhibit the existence regions of these objects in comparison with the angular invariants associated to them.

We give a complete set of orthogonal invariants for tetrahedra in G 2(R8). As a consequence, we characterise regular tetrahedra and we exhibit the existence regions of these objects in comparison with the angular invariants associated to them.
