Domain: Permutation statistics

Details
  • Defined over Permutation as an expression in _x, evaluated by compute-engine — the definition IS the implementation.
  • Takes a Permutation and nothing else — it reads values against their positions, or walks the orbits, so it needs the bijection. Applying it to a bare list is a type error, not a wrong answer.
  • Wolfram's PermutationOrder. The bare Order is Wolfram's canonical-ordering comparison Order[a, b], so this head replaces it. The old name is recorded in formerly but does not resolve: Order(p) is now Wolfram's Order.
