The possibility that a Rayleigh-Taylor instability may lead to an early fragmentation of a supernova shell is investigated by means of 1-, 2-, and 3-dimensional hydrodynamic simulations. In particular, a 'point ' explosion in a n = 3 polytrope is considered, but, in contrast to recent simulations with smoothed particle hydrodynamics, no evidence was found for fragmentation of the shell. These results are in accord with analytic considerations.
