## Abstract It is known that all doublyβeven selfβdual codes of lengths 8 or 16, and the extended Golay code, can be constructed from some binary Hadamard matrix of orders 8, 16, and 24, respectively. In this note, we demonstrate that every extremal doublyβeven selfβdual [32,16,8] code can be const
## Abstract There are exactly 60 inequivalent Hadamard matrices of order 24. In this note, we give a classification of the selfβdual π½~5~βcodes of length 48 constructed from the Hadamard matrices of order 24. Β© 2004 Wiley Periodicals, Inc.
