Streszczenie
A class of subsets of $\mathbb{R}^n$ 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 $(\dim_{\rm H}(U), \underline{\dim}_{\rm B}(U), \overline{\dim}_{\rm B}(U))=(r, s, t)$. Moreover, $2^{-n}\leq H^{r}(K)\leq 2n^{{r}/{2}}$.
