We can take any word and rearrange all the letters to get another “word”. These new “words” may be nonsensical. For example, you can rearrange the letters in MATH to get MTHA. Geordie wants to rearrange all the letters in the word CADET. However, he uses the following rules:
• the letters A and D must be beside each other, and
• the letters E and T must be beside each other.
