Abstract. A regular cover of a connected graph is called dihedral if its transformation group is dihedral. In this paper the author classifies all dihedral coverings of the complete graph K5 whose fibre-preserving automorphism subgroups act arc-transitively.
Keywords: symmetric graphs; s-regular graphs; regular coverings.
