摘要：

- We characterize the number of points for which there exist non-empty Terracini sets of points in P- n . Then, we study minimally Terracini finite sets of points in P- n , and we obtain a complete description, in the case of P- 3 , when the number of points is less than twice the degree of the linear system.
