**Three-dimensional identity symmetry**, also known as **monic symmetry** and notated as **I×I×I**, is a 3D spherical symmetry group. It is the symmetry group of the irregular tetrahedron and is equivalent to the identity group which has no symmetry. It therefore appears as a subgroup of any polyhedral symmetry.
