a generalized quadrangle is an incidence structure whose main feature is the lack of any triangles (yet containing many quadrangles). A generalized quadrangle...

studied as combinatorial objects. A polar space of rank two is a generalized quadrangle; in this case, in the latter definition, the set of points of a...
