Query: A birational embedding with two Galois points for certain Artin-Schreier
  curves   We show that two curves of Artin-Schreier type have a birational embedding
into a projective plane with two Galois points. As a consequence, all curves
with large automorphism groups in the classification list by Henn have a
birational embedding with two Galois points.
