Chiral square symmetry

Chiral square symmetry, also known as kisquare symmetry and notated B2+ or BC2+, is a 2D spherical symmetry group. It is the symmetry group of the square with rotational symmetry but no reflections.

Subgroups

 * K2+ (maximal)
 * I×I

Convex polytopes with BC2+ symmetry

 * Square (regular)
