... thought of. We give, without proof, one example which gives smaller graphs than the ones in the proof of Theorem 12. In this example, calculations are carried modulo 2r + 1. We consider a cycle of ... one-identifying code in G with n − 1 vertices. Proof. We refer to [9], which gives an elegant proof of a more general result.  An easy consequence of Lemma 6 is that T 1 = ∅: Corollary...
