Editing Discrete geometry (section)

==History==
[[Polyhedra]] and [[tessellation]]s had been studied for many years by people such as [[Johannes Kepler|Kepler]] and [[Augustin-Louis Cauchy|Cauchy]], modern discrete geometry has its origins in the late 19th century.  Early topics studied were: the density of [[circle packing]]s by [[Axel Thue|Thue]], [[projective configuration]]s by Reye and [[Ernst Steinitz|Steinitz]], the [[geometry of numbers]] by Minkowski, and [[Four colour theorem|map colourings]] by Tait, Heawood, and [[Hadwiger]].

[[László Fejes Tóth]], [[Harold Scott MacDonald Coxeter|H.S.M. Coxeter]], and [[Paul Erdős]] laid the foundations of ''discrete geometry''.<ref name = "Intuitive">{{Citation
