Chiral heptagonal symmetry

Chiral heptagonal symmetry, also known as kiheggic symmetry and notated as I2(7)+, is a 2D spherical symmetry group. It is the symmetry group of the heptagon with rotational symmetry but no reflections.

Subgroups

 * Identity symmetry (maximal)

Convex polytopes with I2(7)+ symmetry

 * Heptagon (regular)
