A 2-D Affine Geometry constructed over a Finite Field. For a Field of size , the affine plane consists of the set of points which are ordered pairs of elements in and a set of lines which are themselves a set of points. Adding a Point at Infinity and Line at Infinity allows a Projective Plane to be constructed from an affine plane. An affine plane of order is a Block Design of the form (, , 1). An affine plane of order exists Iff a Projective Plane of order exists.
