In this paper, we prove that the normalization of the $G$-orbit Hilbert scheme $\Hilb^G(¶^{r-1})$ is described as a toric variety, which corresponds to the Gröbner fan for some homogeneous ideal $I$ of $K[x_1, ..., x_r]$.13 pages, 3 figuresAlgebraic GeometryCommutative Algebra13P10; 14L30; 14E15; 14M25Hilbert schemes of finite abelian group orbits and Grobner fanstext
