Some Remarks on the Group of Isometries of a Metric Space,n result contained in Theorem?4.1 and Theorem?4.2 is that in case .≠2 all these groups are isomorphic and, consequently, they are independent of?.. In the last section, the isometry dimension of a finite group with respect to a given metric on the space ?. is introduced.
