摘要
We consider the problem of determining the carclinality psi(H-2,H-k) of minimal doubly resolving sets of Hamming graphs H-2,H-k. We prove that for k >= 6 every minimal resolving set of H-2,H-k is also a doubly resolving set, and, consequently psi(H-2,H-k) is equal to the metric dimension of H-2,H-k, which is known from the literature. Moreover, we find an explicit expression for the strong metric dimension of all Hamming graphs H-n,H-k.
