are classified into 7 crystal systems based on cell parameters. [1] They are the basis of the classification of cystals: One can for example count the number of axes of rotation and their respective multiplicities in order to compare different crystals in regard of their symmetry. Looks like you’ve clipped this slide to already.

Bravais lattice is a set of points constructed by translating a single point in discrete steps by a set of basis vectors. << /Length 1 0 R /Filter /FlateDecode >> All rights reserved. In 1848, the French physicist and crystallographer Auguste Bravais (1811-1863) established that in three-dimensional space only fourteen different lattices may be constructed.

The seven crystal systems are a method of classifying crystals according to their atomic lattice or structure.
