I found out the hard way that you can't even reduce a four-entry array down to three entries within the constraints of our universe. I was trying to reduce {4, 4, 4, 4} and made relatively infinmitesimal progress before reaching a most contained array of {4, 4, 4>4>(4>4>256), 2}. At that point I was like "NOPE" and gave up.
