Extended generalized quadrangles

Geometriae Dedicata, 1990
Extended generalized quadrangles (roughly, connected structures whose every residue is a generalized quadrangle) are studied in some detail, especially those which are uniform or strongly uniform. Much basic structure theory is developed, many examples are given, and something approaching characterization is given for many types.

Symmetry in Generalized Quadrangles

Designs, Codes and Cryptography, 2003
In this paper some new points of view about Lenz(-Barlotti)-type classification of finite generalized quadrangles are described. Also, it is shown that each span-symmetric generalized quadrangle of order \(s>1\) with \(s\) even is isomorphic to \(Q(4,5)\) without using the canonical connection between groups of order \(s^3-s\) with a 4-gonal basis and ...

Finite Moufang generalized quadrangles

Journal of Mathematical Sciences, 2006
In 2002, the full classification of generalized polygons appeared [in \textit{J. Tits} and \textit{R. M. Weiss}, Moufang polygons. Springer Monographs in Mathematics. Berlin: Springer (2002; Zbl 1010.20017)]. In this paper it are reviewed some equivalent Moufang conditions for (finite) generalized quadrangles and the geometric classification in the ...
