Propentagonal antiprismatic symmetry

Propentagonal antiprismatic symmetry, also known as propappic symmetry and notated as (I2(10)+×A1)/2, is a 3D spherical symmetry group. It is the symmetry of the pentagonal antiprism if the bases are considered to have chiral rather than full triangular symmetry.
