Abstract: The present paper presented an algrithom to find generator matrices of extremal selfdual binary codes of length 38 with the automorphisms of type 3-(12,2). By implementing Visual C++ procedures, we obtained such new extremal codes and determined the codes to meet the weight enumerator W2.

Key words: extremal selfdual binary code, automorphism, weight enumerator
