In this paper we consider the existence of perfect codes in the infinite class of distance-transitive graphsOk. Perfect 1-codes correspond to certain Steiner systems and necessary conditions for the existence of such a code are satisfied ifk+ 1 is prime. We give some nonexistence results for perfect 2-, 3-, and 4-codes and for perfecte-codes in general, including a lower bound forkin terms ofe.
