👉 Trirhombohedral is a concept in physics and chemistry that describes a shape formed when three or more non-intersecting, rigid tetrahedra are joined together. It's named after the triangular prisms of this shape, which can be used to model various configurations in solid-state physics. A trirhombohedral structure would involve the formation of a three-dimensional structure where each face is composed of two tetrahedra (triangles) that share one vertex and are
