Abstract:
We give a common construction for the product and the glued near polygons by generalizing the glueing construction given in [5]. We call the near polygons arising from this generalized glueing construction decomposable or (again) glued. We will study the geodetically closed sub near polygons of decomposable near polygons. Each decomposable near hexagon has a nice pair of partitions in geodetically closed near polygons. We will give a characterization of the decomposable near polygons using this property.
