Chiral octagonal symmetry

Chiral octagonal symmetry, also known as kioccic symmetry and notated I2(8)+, is a 2D spherical symmetry group. It is the symmetry group of the octagon with rotational symmetry but no reflections.

Subgroups

 * Chiral square symmetry (maximal)
 * Inversion symmetry
 * Identity symmetry

Convex polytopes with I2(8)+ symmetry

 * Octagon (regular)
