Galois geometry

The Fano plane, the projective plane over the field with two elements, is one of the simplest objects in Galois geometry.

Galois geometry (so named after the 19th century French Mathematician Évariste Galois) is the branch of finite geometry that is concerned with algebraic and analytic geometry over a finite field (or Galois field).^[1] More narrowly, a Galois geometry may be defined as a projective space over a finite field.^[2]

Objects of study include vector spaces, affine and projective spaces over finite fields and various structures that are contained in them. In particular, arcs, ovals, hyperovals, unitals, blocking sets, ovoids, caps, spreads and all finite analogues of structures found in non-finite geometries.
