Proof step 19 from proof subst-SK-equal (previous step)

S _ v3 _ v4 _ v5 = C0[K _ v _ v0], value(v3), value(v4), value(v5), value(v), value(v0), context(C0) ⊦ v3 _ v5 _ (v4 _ v5) = C0[v]

User applied rule constructor cut

And obtained the following new goals

Proof step 2:
⊦ O[t] = t
Proof step 16:
C0 = C _ t, S _ v3 _ v4 _ v5 = C0[K _ v _ v0], value(v3), value(v4), value(v5), value(v), value(v0), context(C0) ⊦ v3 _ v5 _ (v4 _ v5) = C0[v]
Proof step 17:
⊦ (t1 _ C)[t] = t1 _ C[t]
Proof step 18:
⊦ ¬ value(C[K _ t _ t0])

Rule argument

[var-arg: C0]
