A 3×3×3 already has multiple such solutions. The center squares can rotate over 90° without visible changes. See https://de.speedcube.com.au/blogs/speedcubing-solutions/how-...

That’s interesting. I originally thought these were isomorphic to rotating the entire cube but of course that doesn’t take into account cases where they rotate relative to each other
