  2. Fano plane - Wikipedia

    en.wikipedia.org/wiki/Fano_plane

    One can similarly construct projective planes over any other finite field, with the Fano plane being the smallest. Using the standard construction of projective spaces via homogeneous coordinates , the seven points of the Fano plane may be labeled with the seven non-zero ordered triples of binary digits 001, 010, 011, 100, 101, 110, and 111.

  3. Incidence geometry - Wikipedia

    en.wikipedia.org/wiki/Incidence_geometry

    If P is a finite set, the projective plane is referred to as a finite projective plane. The order of a finite projective plane is n = k – 1, that is, one less than the number of points on a line. All known projective planes have orders that are prime powers. A projective plane of order n is an ((n 2 + n + 1) n + 1) configuration. The smallest ...

  4. Projective geometry - Wikipedia

    en.wikipedia.org/wiki/Projective_geometry

    In incidence geometry, most authors [16] give a treatment that embraces the Fano plane PG(2, 2) as the smallest finite projective plane. An axiom system that achieves this is as follows: (P1) Any two distinct points lie on a line that is unique. (P2) Any two distinct lines meet at a point that is unique.

  5. Galois geometry - Wikipedia

    en.wikipedia.org/wiki/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 (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]

  6. Projective plane - Wikipedia

    en.wikipedia.org/wiki/Projective_plane

    The Fano plane, discussed below, is denoted by PG(2, 2). The third example above is the projective plane PG(2, 3). The Fano plane. Points are shown as dots; lines are shown as lines or circles. The Fano plane is the projective plane arising from the field of two elements. It is the smallest projective plane, with only seven points and seven lines.

  7. PSL (2,7) - Wikipedia

    en.wikipedia.org/wiki/PSL(2,7)

    In mathematics, the projective special linear group PSL(2, 7), isomorphic to GL(3, 2), is a finite simple group that has important applications in algebra, geometry, and number theory. It is the automorphism group of the Klein quartic as well as the symmetry group of the Fano plane.

    The Airbus A350 was landing at Tokyo’s Haneda airport when it was in collision with a much smaller plane working for the Japanese coastguard in earthquake relief. Tragically, five of the six ...

  9. Steiner system - Wikipedia

    en.wikipedia.org/wiki/Steiner_system

    The Fano plane is a Steiner triple system S(2,3,7). The blocks are the 7 lines, each containing 3 points. Every pair of points belongs to a unique line. In combinatorial mathematics, a Steiner system (named after Jakob Steiner) is a type of block design, specifically a t-design with λ = 1 and t = 2 or (recently) t ≥ 2.
