Letbe a smooth plane curve, andbe all inner and outer Galois points for. Each Galois pointdetermines a Galois group at, say. Then, by the definition of Galois point, an element of the Galois groupinduces a birational transformation of. In fact, we see that it becomes an automorphism of. We call this an automorphism belonging to the Galois point. Then, we consider the groupgenerated by automorphisms belonging to all Galois points for. In particular, we investigate the difference betweenand, so that we determine the structure of.
