THE S6-SYMMETRY OF QUADRANGLES Diplomarbeit vorgelegt
... (cf. Remark 1.6 and Corollary 1.10). We proceed in the same way with quadrangles, where we consider the set X Q of quadrangles with ordered vertices up to affine transformations. Besides the canonical operation of S4 on this set, given by the permutations of the vertices of a quadrangle, there is an ...
