>What type of compact manifolds, can be acted freely by symmetric group $S_{m}$ for some $m>2$? >Is there a compact manifold which can be act freely by all symmetric groups $S_{m}$? This question have been asked already [here](http://math.stackexchange.com/questions/981053/free-action-of-symmetric-group) and is indirectly related to [this](http://mathoverflow.net/questions/184814/a-possible-generalization-of-the-borsuk-ulam-theorem-via-action-of-symmetric-gro).
