Abstract.We introduce self-dual codes over the Kleinian four group K=Z2×Z2 for a natural quadratic form on Kn and develop the theory. Topics studied are: weight enumerators, mass formulas, classification up to length 8, neighbourhood graphs, extremal codes, shadows, generalized t-designs, lexicographic codes, the Hexacode and its odd and shorter cousin, automorphism groups, marked codes. Kleinian codes form a new and natural fourth step in a series of analogies between binary codes, lattices…

It is proved that the minimum distance of a self-dual additive code is related to the minimum vertex degree in the associated graph orbit, and it is shown that some of these codes have highly regular graph representations.

It is shown that quantum error-correcting codes, those of the stabilizer type, are related to Lorentzian lattices and non-chiral CFTs, and thus Narain C FTs are defined.

WEIGHT POLYNOMIALS OF SELF-DUAL CODES AND THE MacWILLIAMS IDENTITIES
- Computer Science
- 1970
The MacWilliams identities are extended to self-dual codes over larger fields and it is shown that this restriction, for codes over GF(2) and GF(3), is that the weight polynomial must lie in an explicitly described free polynometric ring.
