If one of the code words of a Hamming (7, 4) code is 0001011, which of the following cannot be the valid codeword in the same group?

If one of the code words of a Hamming (7, 4) code is 0001011, which of the following cannot be the valid codeword in the same group? Correct Answer 0011010

The minimum bits change between any valid Hamming codes is 3.

Analysis:

The change of bits between the given code: 0001011 and option C code: 0011010 is two bits change only.

So 0011010 can’t be a valid Hamming code of the same group.
