Theorem: LO.FirstOrder.Arith.Model.Seq.isempty_of_lh_eq_zero (Arithmetization/ISigmaOne/HFS/Seq.lean)

State before:
M : Type u_1
inst✝⁵ : Zero M
inst✝⁴ : One M
inst✝³ : Add M
inst✝² : Mul M
inst✝¹ : LT M
inst✝ : M ⊧ₘ* 𝐈𝚺₁
s : M
Hs : Seq s
h : lh s = 0
⊢ s = ∅
Tactic:
simpa [h] using Hs.domain_eq
State after:
