We have encoded messages by assigning the letters of the alphabet the numbers 1-26, with a blank assigned the number 27, and by using an encoding matrix A that converts the numbers to the coded message. To decode any message encoded by A, we must find the inverse of A, denoted by A^-1, and multiply A^-1 times the coded message. Use this code and the given encoding matrix A to find the matrix that can be used to decode the given message.
Code matrix is
The message is

138, 59, 72, 29, 143, 58, 57, 24, 101, 44
