چکیده
We show that there is no [24, 12, 9] doubly-even self-dual code over F4 by attempting to construct the generator matrix of this code directly.

Automorphisms of doubly-even self-dual binary codes
The automorphism group of a binary doubly-even self-dual code is always contained in the alternating group. On the other hand, given a permutation group G of degree n there exists a doubly-even self-dual G-invariant code if and only if n is a multiple of 8, every simple self-dual F2G-module occurs with even multiplicity in F n 2 , and G is contained in the alternating group.
متن کاملSome Results on Type IV Codes Over
Dougherty, Gaborit, Harada, Munemasa, and Solé have previously given an upper bound on the minimum Lee weight of a Type IV self-dual -code, using a similar bound for the minimum distance of binary doubly even self-dual codes. We improve their bound, finding that the minimum Lee weight of a Type IV self-dual -code of length is at most 4 12 , except when = 4, and = 8 when the bound is 4, and = 16...
متن کاملAn Extremal Doubly Even Self-Dual Code of Length 112
In this note, an extremal doubly even self-dual code of length 112 is constructed for the first time. This length is the smallest length for which no extremal doubly even self-dual code of length n 6≡ 0 (mod 24) has been constructed.
متن کاملThe extended quadratic residue code is the only (48, 24, 12) self-dual doubly-even code
The largest minimum weight of a self-dual doubly-even binary (n, k, d) code is d = 4bn/24c+ 4. Of such codes with length divisible by 24, the Golay Code is the only (24, 12, 8) code, the Extended Quadratic Residue Code is the only known (48, 24, 12) code, and there is no known (72, 36, 16) code. One may partition the search for a (48, 24, 12) self-dual doubly-even code into 3 cases. A previous ...
متن کاملOn a 5-design related to a putative extremal doubly even self-dual code of length a multiple of 24
By the Assmus and Mattson theorem, the codewords of each nontrivial weight in an extremal doubly even self-dual code of length 24m form a self-orthogonal 5-design. In this paper, we study the codes constructed from self-orthogonal 5-designs with the same parameters as the above 5-designs. We give some parameters of a self-orthogonal 5-design whose existence is equivalent to that of an extremal ...
