To certain higher rank Cuntz algebras ${mathcal{O}}_n $ including the classical cases we trace a certain partial isometryU in its strong closure. AdjoiningU to ${mathcal{O}}_n $ we obtain a kind of uniqueness property for this largerC *-algebra. Its explanation is not entirely “Cuntz’s uniqueness argumentation”.
