The Hurwitz action of the n-braid group B-n on the n-fold product (B-m)(n) of the m-braid group B-m is studied. Using a natural action of B-n on trees with n labeled edges and n + 1 labeled vertices, we determine all elements of the orbit of every n-tuple of the n distinct standard generators of Bn+1 under the Hurwitz action of B-n.
