Given , , and , find a set of codewords (), each of length bits (), such that each of the codewords is at least Hamming distance () away from each of the other codewords.
The Hamming distance between a pair of codewords is the number of binary bits that differ in their binary notation. Consider the two codewords 0x554 and 0x234 and their differences. 0x554 means the hexadecimal number with hex digits , , and , and a hex digit requires four bits:
Since five bits were different, the Hamming distance is .
