# A report on Crystallography and Crystal system

In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point).

- Crystal systemCoordinates in angle brackets or chevrons such as <100> denote a family of directions which are related by symmetry operations. In the cubic crystal system for example, would mean or the negative of any of those directions.

## Cubic crystal system

0 linksIn crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube.

## Bravais lattice

0 linksIn geometry and crystallography, a Bravais lattice, named after, is an infinite array of discrete points generated by a set of discrete translation operations described in three dimensional space by

In two-dimensional space there are 5 Bravais lattices, grouped into four lattice systems, shown in the table below.
