Galois points for the Dickson-Guralnick-Zieve curve

The Dickson-Guralnick-Zieve curve over a finite field has been studied recently by Giulietti, Korchmaros and Timpanella in several points of view. In this short note, the distribution of Galois points for this curve is determined. As a consequence, a problem posed by the present author in the theory of Galois point is modified.
