## On the Subject of Minimizing Morsematics

Get it? Because it's a cheatsheet! I'll see myself out...

Take the 4th and 5th character of the serial number. They will be refered to as A and B respectively.

Always keep all numeric values between 1-26.

Perform each step below in sequence, modifying A and B:
• For every ind. that matches a received letter, +1 to A if it's lit or otherwise +1 to B.
• If A + B is square, +4 to A; otherwise, -4 to B.
• +Largest received letter to A.
• -Any prime received letters to A.
• -Any square received letters to B.
• For any received letters that are / # Bat., - from both A and B.
After performing all steps, perform whatever rule applies below:
• A = B: Transmit A.
• A > B: Transmit A - B.
• A < B: Transmit A + B.
Perfect squares. Prime numbers.
