Hypotheses

Ref	Expression
sticksstones17.1	⊢ (𝜑 → 𝑁 ∈ ℕ0)
sticksstones17.2	⊢ (𝜑 → 𝐾 ∈ ℕ0)
sticksstones17.3	⊢ 𝐴 = {𝑔 ∣ (𝑔:(1...𝐾)⟶ℕ0 ∧ Σ𝑖 ∈ (1...𝐾)(𝑔‘𝑖) = 𝑁)}
sticksstones17.4	⊢ 𝐵 = {ℎ ∣ (ℎ:𝑆⟶ℕ0 ∧ Σ𝑖 ∈ 𝑆 (ℎ‘𝑖) = 𝑁)}
sticksstones17.5	⊢ (𝜑 → 𝑍:(1...𝐾)–1-1-onto→𝑆)
sticksstones17.6	⊢ 𝐺 = (𝑏 ∈ 𝐵 ↦ (𝑦 ∈ (1...𝐾) ↦ (𝑏‘(𝑍‘𝑦))))

Assertion

Ref	Expression
sticksstones17	⊢ (𝜑 → 𝐺:𝐵⟶𝐴)

Distinct variable groups:   𝐴,𝑏   𝐵,𝑏,𝑖,𝑦   𝑔,𝐾,𝑖,𝑦   𝑔,𝑁   ℎ,𝑁   𝑆,ℎ,𝑖   𝑔,𝑍,𝑖,𝑦   𝑔,𝑏   ℎ,𝑏   𝜑,𝑏,𝑖,𝑦

Allowed substitution hints:   𝜑(𝑔,ℎ)   𝐴(𝑦,𝑔,ℎ,𝑖)   𝐵(𝑔,ℎ)   𝑆(𝑦,𝑔,𝑏)   𝐺(𝑦,𝑔,ℎ,𝑖,𝑏)   𝐾(ℎ,𝑏)   𝑁(𝑦,𝑖,𝑏)   𝑍(ℎ,𝑏)

Proof of Theorem sticksstones17

Dummy variable 𝑠 is distinct from all other variables.
