    Code.

    Each letter of the alphabet is coded thus: it is first represented in 3-bit mod 4 so that A=000, B=001, C=002, D=003, E=010Z=121 and space = 122. Each 2 is then replaced by and each 3 by a . 0 and 1 remain unchanged so now for example, D= and Z= . The string for each letter then has two check digits put on the end using your matrix in 5.

    Here is the correct question because the first one has same missing thinks:

    Find the coding matrix.

    Each letter of the alphabet is coded thus: it is first represented in 3-bit mod 4 so that A=000, B=001, C=002, D=003, E=010……Z=121 and space = 122. Each 2 is then replaced by a and each 3 by a β . 0 and 1 remain unchanged so now for example, D=00β and Z=1α1 . The string for each letter then has two check digits put on the end using your matrix in 5
