Dueling Flamingos: The Story of the Fonality Christmas Golf Challenge

I've managed to reduce the **Hospelian Arabic to Roman Transform** by one byte.

As a lead-in, I've read most of your nodes at some point (always good reading, btw), and when I first saw Ton's amazing formula, I spent a few moments dissecting it to figure out how it did what it did. Recently, while working on a similar problem, I decided to see if I could *reproduce* his formula, armed with the knowledge of how it worked.

A few hours of brute forcing later, and I had a result. Naturally, I wanted to check back here to see how I had done. I was pleasantly surprised to find that I had stumbled upon a formula that was one byte shorter!

**Ton's original formula:**

`y/CLXVI6240-9/MDCLXXVI/dfor$$_.=5x$&*8%29628`

**The one byte improvement:**

`y/CLXVI60-9/MDCLXVIX/dfor$$_.="32e$&"%72726`

**Alternative:**

`y/CLXVI0-9/MDCLXIXV/dfor$$_.="57e$&"%474976`

Even though `"32e$&"%72726` is one byte longer than Ton's `5x$&*8%29628`, it saves 2 bytes in the transliteration, because `01` is transliterated with `IX`. The alternative transliterates `012` with `IXV`, saving yet another byte, but it uses a modulus that's one digit longer.

**Update:**

Since originally posting, I've found several more alternatives of the same length, using multiple substitutions for `I` and/or `V`:

`y/CLXVI0-9/MDCLXIVXI/dfor$$_.="49e$&"%87971
y/CLXVI0-9/MDCLXIIXIV/dfor$$_.="7e$&"%10606 #
y/CLXVI0-9/MDCLXIIXIV/dfor$$_.="7e$&"%15909 #
y/CLXVI0-9/MDCLXIIXIV/dfor$$_.="7e$&"%31818 # These are all essential
+ly the same
y/CLXVI0-9/MDCLXIIX V/dfor$$_.="8e$&"%61535 # Doesn't contain 3 anywh
+ere
# although this is one byte longer, it saved a byte in the challenge I
+ was working on
y/CLXVI60-9/MDCLXXI V/dfor$$_.="37e$&"%97366 # Doesn't contain 1 anywh
