Theorem prmind2 16652

Description: A variation on prmind 16653 assuming complete induction for primes. (Contributed by Mario Carneiro, 20-Jun-2015.)

**Hypotheses**
Ref	Expression
prmind.1	⊢ (𝑥 = 1 → (𝜑 ↔ 𝜓))
prmind.2	⊢ (𝑥 = 𝑦 → (𝜑 ↔ 𝜒))
prmind.3	⊢ (𝑥 = 𝑧 → (𝜑 ↔ 𝜃))
prmind.4	⊢ (𝑥 = (𝑦 · 𝑧) → (𝜑 ↔ 𝜏))
prmind.5	⊢ (𝑥 = 𝐴 → (𝜑 ↔ 𝜂))
prmind.6	⊢ 𝜓
prmind2.7	⊢ ((𝑥 ∈ ℙ ∧ ∀𝑦 ∈ (1...(𝑥 − 1))𝜒) → 𝜑)
prmind2.8	⊢ ((𝑦 ∈ (ℤ_≥‘2) ∧ 𝑧 ∈ (ℤ_≥‘2)) → ((𝜒 ∧ 𝜃) → 𝜏))

**Assertion**
Ref	Expression
prmind2	⊢ (𝐴 ∈ ℕ → 𝜂)

Distinct variable groups: 𝑥,𝑦 𝑥,𝐴 𝑥,𝑧,𝜒 𝜂,𝑥 𝜏,𝑥 𝜃,𝑥 𝑦,𝑧,𝜑 Allowed substitution hints: 𝜑(𝑥) 𝜓(𝑥,𝑦,𝑧) 𝜒(𝑦) 𝜃(𝑦,𝑧) 𝜏(𝑦,𝑧) 𝜂(𝑦,𝑧) 𝐴(𝑦,𝑧)

Proof of Theorem prmind2 Dummy variables 𝑘 𝑛 are mutually distinct and distinct from all other variables.
