In the case of $\Bbb P(1,4)$ there is only one $k$-point with a nontrivial automorphism group, and it is the group of fourth roots of unity. In the case of $\Bbb P(2,3)$ there are exactly two $k$-points with nontrivial automorphism groups--the second roots of unity and the third roots of unity respectively. | |
