Proof step 32 from proof nextli-lemma (previous step)

⊦ ∃ lf. lf(0) = [] ∧ (∀ m. m < n → lf(m + 1) = nextli(lf(m)))

User applied rule structural induction

And obtained the following new goals

Proof step 33:
⊦ ∃ lf. lf(0) = [] ∧ (∀ m. m < 0 → lf(m + 1) = nextli(lf(m)))
Proof step 35:
∀ nextli. ∃ lf. lf(0) = [] ∧ (∀ m. m < n0 → lf(m + 1) = nextli(lf(m))) ⊦ ∃ lf. lf(0) = [] ∧ (∀ m. m < n0 +1 → lf(m + 1) = nextli(lf(m)))

Rule argument

indvar: n
