Theorem hsmexlem4 9882

Description: Lemma for hsmex 9885. The core induction, establishing bounds on the order types of iterated unions of the initial set. (Contributed by Stefan O'Rear, 14-Feb-2015.)

**Hypotheses**
Ref	Expression
hsmexlem4.x	⊢ 𝑋 ∈ V
hsmexlem4.h	⊢ 𝐻 = (rec((𝑧 ∈ V ↦ (har‘𝒫 (𝑋 × 𝑧))), (har‘𝒫 𝑋)) ↾ ω)
hsmexlem4.u	⊢ 𝑈 = (𝑥 ∈ V ↦ (rec((𝑦 ∈ V ↦ ∪ 𝑦), 𝑥) ↾ ω))
hsmexlem4.s	⊢ 𝑆 = {𝑎 ∈ ∪ (𝑅₁ “ On) ∣ ∀𝑏 ∈ (TC‘{𝑎})𝑏 ≼ 𝑋}
hsmexlem4.o	⊢ 𝑂 = OrdIso( E , (rank “ ((𝑈‘𝑑)‘𝑐)))

**Assertion**
Ref	Expression
hsmexlem4	⊢ ((𝑐 ∈ ω ∧ 𝑑 ∈ 𝑆) → dom 𝑂 ∈ (𝐻‘𝑐))

Distinct variable groups: 𝑎,𝑐,𝑑,𝐻 𝑆,𝑐,𝑑 𝑈,𝑐,𝑑 𝑎,𝑏,𝑧,𝑋 𝑥,𝑎,𝑦 𝑏,𝑐,𝑑,𝑥,𝑦,𝑧 Allowed substitution hints: 𝑆(𝑥,𝑦,𝑧,𝑎,𝑏) 𝑈(𝑥,𝑦,𝑧,𝑎,𝑏) 𝐻(𝑥,𝑦,𝑧,𝑏) 𝑂(𝑥,𝑦,𝑧,𝑎,𝑏,𝑐,𝑑) 𝑋(𝑥,𝑦,𝑐,𝑑)

Proof of Theorem hsmexlem4 Dummy variables 𝑒 𝑓 are mutually distinct and distinct from all other variables.
