Proof step 8 from proof inos-greater-rem (previous step)

∀ n. inodekey(n) ∈ ri → n < maxino ⊦ ∀ n0. n0 ∈ (ri \ ks).inos → n0 < maxino

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 9:
inodekey(n) ∈ ri, maxino ≤ n, ∀ n. inodekey(n) ∈ ri → n < maxino ⊦ inodekey(n) ∈ ks

Rule argument

Additional information

Used simplifier rules: inos-node-store-def: ⊦ n ∈ ri.inos ↔ inodekey(n) ∈ ri;% ⊦ m < n ↔ ¬ n ≤ m; (ss)% ⊦ key ∈ ri \ ks ↔ key ∈ ri ∧ ¬ key ∈ ks; (ws)
