A graph L is called a link graph if there is a graph G such that for each vertex of G its neighbors induce a subgraph isomorphic to L. Such a G is said to have constant link . L Sabidussi proved that for any finite group F and any n ⩾ 3 there are infinitely many n ‐regular connected graphs G with Aut G ≅ Γ. We will prove a stronger result: For any finite group Γ and any link graph L with at least one isolated vertex and at least three vertices there are infinitely many connected graphs G with constant link L and Aut G ≅ Γ.
