WebLEMMA 3.4. (Baer [2].) A polarity 0 of a finite projective plane of order n has at least n + 1 absolute points. If this number is n + 1, 0 is orthogonal; if it is greater than n + 1, then n is a square. A polarity 0 of a finite projective plane is called regular if every nonabsolute http://math.ucdenver.edu/~wcherowi/courses/m6406/cslnc.html

WebMar 24, 2024 · The Fano plane is the configuration consisting of the two-dimensional finite projective plane over GF(2) ("of order two"), illustrated above. It is a block design with nu=7, k=3, lambda=1, r=3, and b=7, the Steiner triple system S(7), and the unique 7_3 configuration. The Levi graph of the Fano plane is the Heawood graph.
