Abstract:
We prove that there are only finitely many symmetrical $2$-extensions of a locally finite graph whenever the automorphism group of the graph has an abelian subgroup of finite index (this case is of interest for certain applications). Some refinements and generalizations of this result are also given.
Keywords:
graph, group of automorphisms, symmetrical extension of graphs.
