Description	We consider a Hamiltonian with N point interactions in R-d, d = 2, 3, all with the same coupling constant, placed at vertices of an equilateral polygon P-N. It is shown that the ground-state energy is locally maximized by a regular polygon. The question whether the maximum is global is reduced to an interesting geometric problem.
