Physique, 42:413 A condition is derived, namely (k11/k33)> 3(k22/k33 - 1), that a geodesic surface, which portrays equilibrium director configurations, exists for a nematic. We note that the stated elastic constants do not satisfy this condition, although we are unclear as to the physical significance of this result
