**Rectangular pyramidal symmetry**, also known as **rectpyric symmetry** or **digonal pyramidal symmetry** and notated as **K _{2}×I**, is a 3D spherical symmetry group. It is the symmetry group of the rectangular pyramid, and corresponds to 2D rectangular symmetry with no additional elements. It is the digonal member of the family of pyramidal symmetries.
