Rewrite each of the axioms of the four-point geometry interchanging the words point and line (and making appropriate adjustments in the grammar and definitions).20 Each of these new axioms is called a plane dual, and the ... A collineation, automorphism, or symmetry of the Fano plane is a permutation of the 7 points that preserves collinearity: that is, it carries collinear points (on the same line) to collinear points. By the Fundamental theorem of projective geometry, the full collineation group (or automorphism group, or symmetry group) is the projective linear group PGL(3,2), also denoted . Since the field has only one nonzero element, this group is isomorphic to the projective special linear group PSL(3,2) and …
