Fano subplanes A Fano subplane is a subplane isomorphic to PG(2,2), the unique projective plane of order 2. If you consider a quadrangle (a set of 4 points no three collinear) in this plane, the points determine six of the lines of the plane.
Gino Fano (1871–1952), in developing a new set of axioms for Euclidean geometry, took as an axiom that the diagonal points of any quadrangle are never collinear.
An open question is: Does every non-desarguesian plane contain a Fano subplane?
This formalism was described in a monograph coauthored by his cousin Ugo Fano (Irreducible Tensorial Sets, 1959).
Examples * Tunnel junction is characterized by low transmission in all transport channels, therefore the electron flow is Poissonian, and the Fano factor equals one.
