Generator Matrix Based Search for Extremal Self-Dual Binary Error-Correcting Codes
… doubly even linear binary error-correcting codes, often referred to as Type II codes, are codes closely related to many combinatorial structures such as 5-designs. Extremal codes are codes that have the largest possible minimum distance for a given length and dimension. The existence of an …

Automorphism groups of self-dual codes
This thesis treats linear block codes, which are classically used in the storage and transmission of digital information. The dual of such a code is the orthogonal space with respect to a Euclidian or Hermitian scalar product. A code which equals its dual is called self-dual. Self-dual codes are of …
