**Affine Cipher Exercise**

In this exercise, you will use a software tool to perform calculations, but it's essential to document your process thoroughly.

### Correspondence of Letters Table

| Letter | A  | B  | C  | D  | E  | F  | G  | H  | I  | J  | K  | L  | M  |
|--------|----|----|----|----|----|----|----|----|----|----|----|----|----|
| Value  | 01 | 02 | 03 | 04 | 05 | 06 | 07 | 08 | 09 | 10 | 11 | 12 | 13 |

| Letter | N  | O  | P  | Q  | R  | S  | T  | U  | V  | W  | X  | Y  | Z   | space |
|--------|----|----|----|----|----|----|----|----|----|----|----|----|-----|-------|
| Value  | 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26  | 00    |

### Problem Statement

1. Encipher the message "GEAUX TIGERS" using the affine transformation:

   \[
   y \equiv 11x + 18 \pmod{27}
   \]

This exercise will guide you through using the correspondence table alongside the affine transformation to encrypt a simple message. Be sure to document each step meticulously.
