fact: Example ex_categorical (C : Category) (x y z w : C) (f : z ~> w) (g : y ~> z) (h : x ~> y) (i : x ~> z) : g ∘ id ∘ id ∘ id ∘ h ≈ i -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ id ∘ id ∘ id ∘ h ≈ g ∘ h -> g ∘ h ≈ i -> f ∘ (id ∘ g ∘ h) ≈ (f ∘ g) ∘ h.
