SUMMARY
The discussion centers on the properties of Hamming (7,4) codes, specifically addressing the impossibility of a codeword differing from a valid codeword by exactly two bits. Given that the minimum Hamming distance for the (7,4) code is 3, any codeword must differ from another valid codeword by at least this distance. Therefore, a codeword that differs from a valid codeword at two bits cannot exist within the constraints of Hamming (7,4) coding.
