data Trichotomous : (a -> a -> Type) -> (a -> a -> Type) -> (a -> a -> Type) -> a -> a -> Type

  Trichotomous formalises the fact that three relations are mutually exclusive.
  It is meant to be used with relations that complement each other so that the
  `Trichotomous lt eq gt` relation is the total relation.

Totality: total
