The stability of hexagonal convection cells is analyzed in the case of a Boussinesq fluid heated from below with symmetric rigid horizontal boundaries. For $P>1.2$ a region of stable hexagon convection appears for α<αc and R2Rc where P, α, R are the Prandtl number, the wave number, and the Rayleigh number. The theoretical results are in agreement with recent experimental observations by Assenheimer and Steinberg [Phys. Rev. Lett. 76, 756 (1996)].
