Theorem cshweqrep 14778

Description: If cyclically shifting a word by L position results in the word itself, the symbol at any position is repeated at multiples of L (modulo the length of the word) positions in the word. (Contributed by AV, 13-May-2018.) (Revised by AV, 7-Jun-2018.) (Revised by AV, 1-Nov-2018.)

**Assertion**
Ref	Expression
cshweqrep	⊢ ((𝑊 ∈ Word 𝑉 ∧ 𝐿 ∈ ℤ) → (((𝑊 cyclShift 𝐿) = 𝑊 ∧ 𝐼 ∈ (0..^(♯‘𝑊))) → ∀𝑗 ∈ ℕ₀ (𝑊‘𝐼) = (𝑊‘((𝐼 + (𝑗 · 𝐿)) mod (♯‘𝑊)))))

Distinct variable groups: 𝑗,𝐼 𝑗,𝐿 𝑗,𝑉 𝑗,𝑊

Proof of Theorem cshweqrep Dummy variables 𝑦 𝑥 are mutually distinct and distinct from all other variables.
