Theorem opsrval2 21980

Description: Self-referential expression for the ordered power series structure. (Contributed by Mario Carneiro, 8-Feb-2015.)

**Hypotheses**
Ref	Expression
opsrval2.s	⊢ 𝑆 = (𝐼 mPwSer 𝑅)
opsrval2.o	⊢ 𝑂 = ((𝐼 ordPwSer 𝑅)‘𝑇)
opsrval2.l	⊢ ≤ = (le‘𝑂)
opsrval2.i	⊢ (𝜑 → 𝐼 ∈ 𝑉)
opsrval2.r	⊢ (𝜑 → 𝑅 ∈ 𝑊)
opsrval2.t	⊢ (𝜑 → 𝑇 ⊆ (𝐼 × 𝐼))

**Assertion**
Ref	Expression
opsrval2	⊢ (𝜑 → 𝑂 = (𝑆 sSet ⟨(le‘ndx), ≤ ⟩))
