A projective plane is an incidence structure which satisfies the following three axioms.

The order of a projective plane is defined to be the unique cardinal number n with for all points p and all lines l, respectively.

Primary examples of projective planes are the projective planes over vector spaces. More general projective planes are coordinatized over ternary fields.
