Digonal antiprismatic prismatic symmetry

Digonal antiprismatic prismatic symmetry, also known as dappipic symmetry and notated (B2×A1)/2×A1 or (BC2×A1)/2×A1, is a 4D spherical symmetry group. It is the symmetry group of the tetragonal disphenoidal prism and is the digonal member of the family of antiprismatic prismatic symmetries.
