LinearOrderedCommGroupWithZero.discrete_or_denselyOrdered

∀ (G : Type u_2) [inst : LinearOrderedCommGroupWithZero G] [Nontrivial Gˣ] [MulArchimedean G],
  Nonempty (G ≃*o WithZero (Multiplicative ℤ)) ∨ DenselyOrdered G

Any nontrivial (has other than 0 and 1) linearly ordered mul-archimedean group with zero is either isomorphic (and order-isomorphic) to ℤᵐ⁰, or is densely ordered.
