Proof step 50 from proof nouninit-addarrays (previous step)

newref_list(i→n(countrefs(ints)), st) = r ' + refs, posints(ints), 0 ≤ i ⊦ (∀ class. class ∈ claset → ¬ initundone(class, addarrays(r ' + refs, ty, ints, i, st))) ↔ (∀ class. class ∈ claset → ¬ initundone(class, st)), ints = []

User applied rule case distinction

And obtained the following new goals

Proof step 24:
∀ class. class ∈ claset → ¬ initundone(class, addarrays(r ' + refs, ty, ints, i, st)), newref_list(i→n(countrefs(ints)), st) = r ' + refs, posints(ints), 0 ≤ i ⊦ ∀ class. class ∈ claset → ¬ initundone(class, st), ints = []
Proof step 49:
∀ class. class ∈ claset → ¬ initundone(class, st), newref_list(i→n(countrefs(ints)), st) = r ' + refs, posints(ints), 0 ≤ i ⊦ ∀ class. class ∈ claset → ¬ initundone(class, addarrays(r ' + refs, ty, ints, i, st)), ints = []
