Proof step 3 from proof inos-greater-notin (previous step)

ri.inos < maxino, inodekey(maxino) ∈ ri ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ ns < n ↔ (∀ n0. n0 ∈ ns → n0 < n)
Proof step 5:
inodekey(maxino) ∈ ri, ∀ n0. n0 ∈ ri.inos → n0 < maxino ⊦

Rule argument

spec: oset, inst: nat-set name: Greater seq: ⊦ ns < n ↔ (∀ n0. n0 ∈ ns → n0 < n) subst: [n, ns] → [maxino, ri.inos] flags: <all paths>

Additional information

Used terms: maxino, ri.inos
