simproc for Nat.primeFactorsList

Note that since norm_num can only produce numerals, we can't register this as a norm_num extension.

def Mathlib.Meta.Simproc.FactorsHelper (n p : ℕ) (l : List ℕ) : Prop

A proof of the partial computation of primeFactorsList. Asserts that l is a sorted list of primes multiplying to n and lower bounded by a prime p.

Equations

• Mathlib.Meta.Simproc.FactorsHelper n p l = (Nat.Prime p → List.IsChain (fun (x1 x2 : ℕ) => x1 ≤ x2) (p :: l) ∧ (∀ (a : ℕ), a ∈ l → Nat.Prime a) ∧ l.prod = n)

The argument explicitness in this section is chosen to make only the numerals in the factors list appear in the proof term.
