Three-way system
The triplet or rhombo system is one of seven crystal systems describing the crystal structure as three vectors. The three-way system has three vectors of the same length, each angle formed by each axis not perpendicular to the shape of the cube in a diagonal direction is stretched. It may be included in the hexagonal system in some cases. There is only one brave lattice of 'simple three-way political system' in the three-way political system. Below is a list of point clouds belonging to the four-sided politics expressed in international notation and 쇤 flece notation.
