  For every irreducible complex representation~$\pi_\lambda$ of the symmetric
group~$\S_n$, we construct, in a canonical way, a so-called intrinsic
hyperplane arrangement~$\A_{\lambda}$ in the space of~$\pi_\lambda$. This
arrangement is a direct generalization of the classical braid arrangement
(which is the special case of our construction corresponding to the natural
representation of~$\S_n$), has a natural description in terms of invariant
subspaces of Young subgroups, and enjoys a number of remarkable properties.
