Abstract:
We determine all distance-2-sets and all valuations of the 11 slim dense near hexagons. We consider this as a necessary step in order to classify all slim dense near octagons. These near octagons will be classified in a forthcoming paper.
Keywords: near polygon, generalized quadrangle, valuation
