A class of subsets of ℝⁿ is constructed that have certain homogeneity and non-coincidence properties with respect to Hausdorff and box dimensions. For each triple (r,s,t) of numbers in the interval (0,n] with r < s < t, a compact set K is constructed so that for any non-empty subset U relatively open in K, we have $(dim_{H}(U), \underline{dim}_{B}(U), \overline{dim}_{B}(U)) = (r,s,t)$. Moreover, $2^{-n} ≤ H^{r}(K) ≤ 2n^{r/2}$.
