Proof step 3 from proof same-subclasses-tdnameex-02 (previous step)

class∃(str0, class0), class0 ≤ class, ∀ class0. interface∃(str0, class0) ∧ class0 ≤ class → interface∃(str, class0), ∀ class0. class∃(str0, class0) ∧ class0 ≤ class → class∃(str, class0) ⊦ tdname∃(str, class0)

Heuristic quantifier closing applied rule all left

And closed the goal!

Rule argument

[EXRARG : pos: left 4, [QUANTTERMLIST : (class0)]]
