  {β : ι → Type u_2} → (ι → ι → Prop) → ({i : ι} → β i → β i → Prop) → ((i : ι) → β i) → ((i : ι) → β i) → Prop

The lexicographic relation on Π i : ι, β i, where ι is ordered by r, and each β i is ordered by s. The < relation on Lex (∀ i, β i) is Pi.Lex (· < ·) (· < ·), while the < relation on Colex (∀ i, β i) is Pi.Lex (· > ·) (· < ·).
