Query: The group of bi-Galois objects over the coordinate algebra of the
  Frobenius-Lusztig kernel of SL(2)   We construct, for q a root of unity of odd order, an embedding of the
projective special linear group PSL(n) into the group of bi-Galois objects over
u_q(sl(n))*, the coordinate algebra of the Frobenius-Lusztig kernel of SL(n),
which is shown to be an isomorphism at n=2.
