Prodigonal antiprismatic symmetry

Prodigonal antiprismatic symmetry, also known as prodappic symmetry and notated (B2+×A1)/2 or (BC2+×A1)/2, is a 3D spherical symmetry group. It is the symmetry group of the tetragonal disphenoid if the top and bottom edges are regarded as having chiral digonal rather tha full igonal symmetry.
