Theorem repsconst 14127

Description: Construct a function mapping a half-open range of nonnegative integers to a constant, see also fconstmpt 5607. (Contributed by AV, 4-Nov-2018.)

Assertion

Ref	Expression
repsconst	⊢ ((𝑆 ∈ 𝑉 ∧ 𝑁 ∈ ℕ0) → (𝑆 repeatS 𝑁) = ((0..^𝑁) × {𝑆}))

Proof of Theorem repsconst
