The problem is reduced to a question about zero-dimensional schemes $Γ\subset {\bf P}^{n-1}$ in symmetric position with certain constrains on the Hilbert function. The method of Gröbner bases is then applied to study the homogeneous ideal of $Γ$.24 pagesAlgebraic GeometryCommutative Algebra14N05, 14H50A Step in Castelnuovo theory via Grobner basestext
