Identity symmetry (3D)

Identity symmetry (3D)
Rank	3
Space	Spherical
Order	1

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.
