Packings of Balls,Atoms may be considered as small rigid balls. The packing of balls is an important concept in crystallography for the description of crystal structures, that is, the arrangement of atoms in a crystal. Many inorganic crystal structures are based on densest packings of balls.

Also classical crystallography in three-dimen sional Euclidean space has been extended to higher dimen sions in order to understand better the dimension independent crystallographic properties. The aim of this note is to introduce the reader to the fascinating and rich world

Basic Definitions,lography. Moreover, such point sets are of great importance in several branches of mathematics and physics. Whereas the existence of a continuum in nature cannot be shown, the discontinuum has an assured position in natural sciences. In this chapter some general properties of discrete point sets will be discussed.
