Proof step 2 from proof log-group-block-id-idx (previous step)

id-idx(lpt0, lpt1), log-group-block(nx, lpt0) ⊦ log-group-block(nx, lpt1)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
id-idx(lpt0, lpt1), n ∈ nx, ∀ n. n ∈ nx → n < # lpt0 ∧ lpt0[n].flags = LP_GROUP_NODES ⊦ n < # lpt1 ∧ lpt1[n].flags = LP_GROUP_NODES

Rule argument

Additional information

Used simplifier rules: log-group-block: ⊦ log-group-block(nx, lpt) ↔ (∀ n. n ∈ nx → n < # lpt ∧ lpt[n].flags = LP_GROUP_NODES);
