Description: Properties of an s-walk of edges. (Contributed by AV, 4-Jan-2021.)

**Hypothesis**
Ref	Expression
ewlksfval.i	⊢ 𝐼 = (iEdg‘𝐺)

**Assertion**
Ref	Expression
ewlkprop	⊢ (𝐹 ∈ (𝐺 EdgWalks 𝑆) → ((𝐺 ∈ V ∧ 𝑆 ∈ ℕ₀^*) ∧ 𝐹 ∈ Word dom 𝐼 ∧ ∀𝑘 ∈ (1..^(♯‘𝐹))𝑆 ≤ (♯‘((𝐼‘(𝐹‘(𝑘 − 1))) ∩ (𝐼‘(𝐹‘𝑘))))))

Distinct variable groups: 𝑘,𝐺 𝑆,𝑘 𝑘,𝐹 Allowed substitution hint: 𝐼(𝑘)

Proof of Theorem ewlkprop Dummy variables 𝑓 𝑔 𝑖 𝑠 are mutually distinct and distinct from all other variables.
