The linked wikipedia article states "If there are multiple operations, operators are given immediately after their second operands"

Added, thank you.

Sorry, it was only my intent to use single-digit integers as operands. I lost my original description and had to rewrite it and forgot to add "single-digit" in the new writeup, but it was a deliberate choice.

Will do.

Well, damn. I searched "cipher" before I started and must've overlooked it.

So, what do I do? Delete this?

I like it. That's some impressive density.
