Characterizations of the G(2)(4) and L-3(4) near octagons Ghent University
A triple (S, S, Q) consisting of a near polygon S, a line spread S of S and a set Q of quads of S is called a polygonal triple if certain nice properties are satisfied, among which there is the requirement that the point-line geometry S' formed by the lines of S and the quads of Q is itself also a near polygon. This paper addresses the problem of classifying all near polygons S that admit a polygonal triple (S, S, Q) for which a given ...
