Theorem sqff1o 26683

Description: There is a bijection from the squarefree divisors of a number 𝑁 to the powerset of the prime divisors of 𝑁. Among other things, this implies that a number has 2↑𝑘 squarefree divisors where 𝑘 is the number of prime divisors, and a squarefree number has 2↑𝑘 divisors (because all divisors of a squarefree number are squarefree). The inverse function to 𝐹 takes the product of all the primes in some subset of prime divisors of 𝑁. (Contributed by Mario Carneiro, 1-Jul-2015.)

**Hypotheses**

sqff1o.1	⊢ 𝑆 = {𝑥 ∈ ℕ ∣ ((μ‘𝑥) ≠ 0 ∧ 𝑥 ∥ 𝑁)}
sqff1o.2	⊢ 𝐹 = (𝑛 ∈ 𝑆 ↦ {𝑝 ∈ ℙ ∣ 𝑝 ∥ 𝑛})
sqff1o.3	⊢ 𝐺 = (𝑛 ∈ ℕ ↦ (𝑝 ∈ ℙ ↦ (𝑝 pCnt 𝑛)))

**Assertion**
Ref	Expression
sqff1o	⊢ (𝑁 ∈ ℕ → 𝐹:𝑆–1-1-onto→𝒫 {𝑝 ∈ ℙ ∣ 𝑝 ∥ 𝑁})
