The decoded cryptogram is REMEMBER SEPTEMBER THE ELEVENTH.
Explanation of Solution
Given information:
First find the inverse of given matrix using augmented with a
Further
Hence
Now divide the given code into groups of 3 in given order and multiply it by inverse matrix
The sequence is 0 18 5 13 5 13 2 5 18 0 19 5 16 20 5 13 2 5 18 0 20 8 5 0 5 12 5 22 5 14 20 8 0 comparing the decoded number with 0 as space and
