65.49 Generating Unrestricted Codes

The following sections start with the description of creating codes from user defined matrices or special matrices (see ElementsCode, HadamardCode, ConferenceCode and MOLSCode). These codes are unrestricted codes; they may later be discovered to be linear or cyclic.

The next section describes a function for generating random codes (see RandomCode).

The next section describes the Nordstrom-Robinson code (see NordstromRobinsonCode).

The last sections describe two functions for generating Greedy codes. These are codes that contructed by gathering codewords from a space (see GreedyCode and LexiCode).
