Streszczenie
We prove that $X$ is a hereditarily indecomposable metric continuum if and only if the $n$-fold hyperspace ${\mathcal C}_n(X)$ does not contain $(n+1)$-cells, for any positive integer $n$. Also we characterize the class of continua whose $n$-fold hyperspaces and $n$-fold hyperspace suspensions are cells.
