Hi Zorflax, thank you for hosting and posting!

While brute forcing my way through this, I was worried it would need to be 6P because the last output needed another atom to duplicate off of. I was then relieved to learn a trick from the Dye Hard weekly - put the catalyst back over the input and it can loop!

There's a ton of blank instruction space and I don't know how to tell when tinkering with something will take 5 minutes or require a complete reprogramming. Arm 10 is helping, it swears!

Thank you!
