Proof step 1 from proof enc-invert (conclusion)

⊦ encode(m.1, m.2) = m

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ m.1 = maxenc(m) - m.2
Proof step 3:
⊦ encode(maxenc(m) - m.2, m.2) = m

Rule argument

spec: nat-pair inst: name: dec-fst seq: ⊦ m.1 = maxenc(m) - m.2 subst: [m] → [m] flags: rewrite, current
