Query: Hyperbolic reflection groups associated to the quadratic forms $-3x_0^2
  + x_1^2 + ... + x_n^2$   We determine the maximal hyperbolic reflection groups associated to the
quadratic forms $-3x_0^2 + x_1^2 + ... + x_n^2$, $n \ge 2$, and present the
Coxeter schemes of their fundamental polyhedra. These groups exist in
dimensions up to 13, and a proof is given that in higher dimensions these
quadratic forms are not reflective.
