Theorem dihord 38402

Description: The isomorphism H is order-preserving. Part of proof after Lemma N of [Crawley] p. 122 line 6. (Contributed by NM, 7-Mar-2014.)

**Hypotheses**
Ref	Expression
dihord.b	⊢ 𝐵 = (Base‘𝐾)
dihord.l	⊢ ≤ = (le‘𝐾)
dihord.h	⊢ 𝐻 = (LHyp‘𝐾)
dihord.i	⊢ 𝐼 = ((DIsoH‘𝐾)‘𝑊)

**Assertion**
Ref	Expression
dihord	⊢ (((𝐾 ∈ HL ∧ 𝑊 ∈ 𝐻) ∧ 𝑋 ∈ 𝐵 ∧ 𝑌 ∈ 𝐵) → ((𝐼‘𝑋) ⊆ (𝐼‘𝑌) ↔ 𝑋 ≤ 𝑌))
