Incidence geometry

Partial geometry

An incidence structure consists of points , lines , and flags where a point is said to be incident with a line if . It is a (finite) partial geometry if there are integers such that: * For any pair of distinct points and , there is at most one line incident with both of them. * Each line is incident with points. * Each point is incident with lines. * If a point and a line are not incident, there are exactly pairs , such that is incident with and is incident with . A partial geometry with these parameters is denoted by . (Wikipedia).
