Let $E \subset \mathbb R^n$. Must the homology groups $H_k (E)$ be trivial for $k \geq n$? How about just for $k > n$? If not, whats an example?

Thanks.

    @Ryan: Nice counterexample! I would have thought that the ‘dimension’ of a subspace would be bounded by the ‘dimension’ of the space, but I guess pathological subspaces can behave badly...2011-12-28

    @Ryan: are there also counterexamples for $k>n$? are the higher singular homology groups of the (n-1)-Hawaian earring known?2011-12-28
