**Digonal prismatic symmetry**, also known as **brick symmetry** or **cuboidal symmetry** and notated as *K _{3}*, is a 3D spherical Coxeter group. It is the symmetry group of the cuboid or rectangular box, and appears as a subgroup of octahedral and icosahedral symmetries.

### Subgroups[edit | edit source]
