چکیده
|
Consider any permutation of the elements of a (finite) metric space that preserves a specific distance p. when is such a permutation automatically an isometry of the metric space? in this note we study this problem for the hamming spaces h(n; q) both from a linear algebraic and combinatorial point of view. we obtain some sufficient conditions for the question to have an affirmative answer, as well as pose some interesting open problems.
