Bravaisrácshoz
Bravaisrácshoz refers to a concept in crystallography related to Bravais lattices and the mathematical group known as the Lorentz group. A Bravais lattice is a three-dimensional, infinite, periodic arrangement of points in space. These lattices are fundamental to describing the structure of crystalline materials. There are 14 unique Bravais lattices, classified by their unit cell shapes and lattice parameters.
The Lorentz group is a group of linear transformations which leave the spacetime interval in Minkowski spacetime
