Can I say that only maximal simplices in a simplicial complex determine the homology group? If not what's wrong?

    $\begingroup$ ... and what do you mean by the homology group, as there are infinitely many homology groups (which may be trivial). You need to expand the question to be more precise. $\endgroup$ – Tim Porter May 16 at 9:29
  • $\begingroup$ The set of maximal faces determines the whole simplicial complex, so in this sense it determines all of its properties. $\endgroup$ – Michal Adamaszek May 16 at 10:09
