Abstract:   A weighting of the edges of a graph is called neighbor distinguishing if the weighted degrees of the vertices yield a proper coloring of the graph. In this note we show that such a weighting is possible from the weight set {1, 2, 3, 4, 5, 6} for all graphs not containing components with exactly 2 vertices.

Keywords:   graph, labelling, coloring, hypergraphs
