Abstract. The vertex-distinguishing index of a graph \(G\) (\(\operatorname{vdi}(G)\)) is the minimum number of colours required to colour properly the edges of a graph in such a way that any two vertices are incident with different sets of colours. We consider this parameter for some families of cubic graphs.
Keywords: edge colouring, vertex-distinguishing colouring, cubic graphs.
