In this article, we investigate the Hamming weight enumerators of self-dual codes over % O and 9 I . Using invariant theory, we determine a basis for the space of invariants to which the Hamming weight enumerators belong for self-dual codes over % O and 9 I .

Moreover, if 0 admits the (t, i)-design property for every i t, we say that 0 admits the t-design property.

New bounds are given for the minimal Hamming and Lee weights of self-dual codes over 9 . For a self-dual code of length n, the Hamming weight is bounded above by 4[n/24]#f (n mod 24), for an explicitly given function f; the Lee weight is bounded above by 8[n/24]#g(n mod 24), for a di!erent function
All [52, 26,10] binary self-dual codes with an automorphism of order 7 are enumerated. Up to equivalence, there are 499 such codes. They have two possible weight enumerators, one of which has not previously arisen. 2001 Academic Press 1. INTRODUCTION In [1], Conway and Sloane present an upper bound
