The purpose of this short note is to show that there is in general no containment I (3)⊂ I 2 for an ideal I of points in P 2. This answers in the negative a question asked by Huneke and generalized by Harbourne. The sets of points constituting counterexamples come from the dual of the Hesse configuration and more generally from Fermat arrangements.
