===Finite geometry===
{{Main|Finite geometry}}

Finite geometry is the study of [[Geometry|geometric systems]] having only a finite number of points. Structures analogous to those found in continuous geometries ([[Euclidean plane]], [[real projective space]], etc.) but defined combinatorially are the main items studied. This area provides a rich source of examples for [[Combinatorial design|design theory]]. It should not be confused with discrete geometry ([[combinatorial geometry]]).
