Abstract
In this paper we characterize the finite sets of points in P^2, arising as a complete intersection of two curves, by means of their realizable sequences. Actually, we show that a reduced 0-dimensional scheme in P^2 is a complete intersection of type (a; b) iff all its realizable sequences can be obtained by means of direct transpositions from a special one .
