The children of the (32, 16) doubly even codes
Vera S. Pless · IEEE Transactions on Information Theory · 1978
Generator matrices, weight distributions, and automorphism groups are given for all (26,13,6), (28,14,6), and (30,15,6) binary self-dual codes. These results are obtained from the earlier enumeration made by J. H. Conway and the author of all (32,16) self-dual doubly even codes.
