Abstract
The Nordstrom-Robinson, Kerdock, and (slightly modified) Preparata codes are shown to be linear over Z4, the integers mod4. The Kerdock and Preparata codes are duals over Z4, and the Nordstrom-Robinson code is self-dual. All these codes are just extended cyclic codes over Z4. This provides a simple definition for these codes and explains why their Hamming weight distributions are dual to each other. First- and second-order Reed-Muller codes are also linear codes over Z4, but Hamming codes in general are not, nor is the Golay code.
