Idea

The (large) precategory of decidable total orders consists of decidable total orders and order preserving maps and is exhibited as a full subprecategory of the precategory of posets.

Definitions

The large precategory of decidable total orders

parametric-Decidable-Total-Order-Full-Large-Subprecategory :
  (α β : Level → Level) →
  Full-Large-Subprecategory
    ( λ l → α l ⊔ β l)
    ( parametric-Poset-Large-Precategory α β)
parametric-Decidable-Total-Order-Full-Large-Subprecategory α β =
