Chiral digonal prismatic symmetry

K3+, also known as kibrick symmetry, chiral brick symmetry, or chiral digonal prismatic symmetry, is a 3D spherical Coxeter group. It is the symmetry group of the rhombic disphenoid, a noble variant of the tetrahedron. It is equivalent to the rotational symmetries of a rectangular box.
