N2 - Let Fn be the binary n-cube, or binary Hamming space of dimension n, endowed with the Hamming distance, and εn (respectively, οn) the set of vectors with even (respectively, odd) weight. For r ≥ 1 and x ∈ Fn, we denote by Br(x) the ball of radius r and centre x. A code C ⊆ F n is said to be r-identifying if the sets Br(x) ∩ C, x ∈ Fn, are all nonempty and distinct. A code C ⊆ εn is said to be r-discriminating if the sets B r(x)∩C, x ∈ οn, are all nonempty and distinct. We show that the two definitions, which were given for general graphs, are equivalent in the case of the Hamming space, in the following sense: for any odd r, there is a bijection between the set of r-identifying codes in F n and the set of r-discriminating codes in Fn+1.
