Doubly-even self-dual code of length 96
Radinka Dontcheva · IEEE Transactions on Information Theory · 2002
We prove that 23, 11, and 7 do not divide the order of the automorphism group of a binary [96, 48, 20] doubly-even self-dual code. We construct 25 new inequivalent binary [96, 48, 16] doubly-even self-dual codes via an automorphism of order 23.
