Propentagonal prismatic symmetry

Propentagonal prismatic symmetry, also known as propippic symmetry and notated as H₂+×A₁, is a 3D spherical symmetry group. It is equivalent to the symmetry of a pentagonal prism if the bases are seen as having chiral pentagonal rather than full pentagonal symmetry.
