You are right, zero fixed points does not mean total structural difference. Your counterexample is good. My wording was wrong, I will
fix it. What interests me is not the statistical rarity, but that 81% of elements are in one orbit — this means the reordering is
highly coupled, not a bunch of small local swaps.

But what is the significance of the reordering being highly coupled?
The observation itself is the value — it tells you the King Wen sequence is not a bunch of small local adjustments, but a holistic
rearrangement. But it cannot tell you why King Wen arranged it this way.
