Description: 𝐺 (see frec2uz0d 9709) is a one-to-one onto mapping. (Contributed by Jim Kingdon, 17-May-2020.)

Hypotheses

Ref	Expression
frec2uz.1	⊢ (𝜑 → 𝐶 ∈ ℤ)
frec2uz.2	⊢ 𝐺 = frec((𝑥 ∈ ℤ ↦ (𝑥 + 1)), 𝐶)

Assertion

Ref	Expression
frec2uzf1od	⊢ (𝜑 → 𝐺:ω–1-1-onto→(ℤ≥‘𝐶))

Distinct variable groups:   𝑥,𝐶   𝜑,𝑥

Allowed substitution hint:   𝐺(𝑥)

Proof of Theorem frec2uzf1od

Dummy variables 𝑦 𝑧 are mutually distinct and distinct from all other variables.
