Abstract
We show that in every commensurability class of cusped arithmetic hyperbolic manifolds of simplest type of dimension there are manifolds such that the Stiefel-Whitney classes are non-vanishing for all . We also show that for the same commensurability classes there are manifolds (different from the previous ones) that do not admit a structure.
