Theorem seqpo 33543

Description: Two ways to say that a sequence respects a partial order. (Contributed by Jeff Madsen, 2-Sep-2009.)

**Assertion**
Ref	Expression
seqpo	⊢ ((𝑅 Po 𝐴 ∧ 𝐹:ℕ⟶𝐴) → (∀𝑠 ∈ ℕ (𝐹‘𝑠)𝑅(𝐹‘(𝑠 + 1)) ↔ ∀𝑚 ∈ ℕ ∀𝑛 ∈ (ℤ_≥‘(𝑚 + 1))(𝐹‘𝑚)𝑅(𝐹‘𝑛)))

Distinct variable groups: 𝑚,𝐹,𝑛,𝑠 𝐴,𝑚,𝑛,𝑠 𝑅,𝑚,𝑛,𝑠

Proof of Theorem seqpo Dummy variables 𝑝 𝑞 are mutually distinct and distinct from all other variables.
