Digonal antiprismatic prismatic symmetry

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