 Abstract. We study the question of whether there is a minimum Hilbert function for double point schemes whose support is s points with generic Hilbert function. Previous work shows that this question has an affirmative answer for  and for  (for any N). In this paper, we provide evidence in the case , and give an affirmative answer to the question when s = 11.
