Prosquare prismatic symmetry

Prosquare prismatic symmetry, also known as prosquippic symmetry and notated B2+×A1 or BC2+×A1, is a 3D spherical symmetry group. It is equivalent of the symmetry of a square prism if the bases are seen as having chiral rather than full square symmetry. The prism of any polygon with chiral square symmetry will have this as its symmetry groupp.
