Consider the ideal I⊆ K [x, y, z] corresponding to points p 1,…, p r of P 2. We study the symbolic generic initial system {gin (I (m))} m of such an ideal and its behaviour as m gets large. In particular, we describe the limiting shape of this system explicitly when p 1,…, p r are generic, assuming that the Uniform SHGH Conjecture holds for r≥ 9. The symbolic generic initial system and its limiting shape reflect information about the asymptotic behaviour of Hilbert functions of fat point ideals.
