    divide each by 4 and 04 is the only byte to give 1

      Mh. There must be something that the other 7 have in common.

      And it’s not easy, so deviding by something seems not to be the answer.

  3. Hint: It has something to do with coding theory. And it is not “junior” as the title claims 😉

  4. The solution is ‘b1’. All bytes have Hamming distance of at least 4 but b1 has just 3 with some of the other bytes.
