Proof step 23 from proof sep-ass (previous step)

((P1 * P2))(H0), P0(H1), H1 ⊥ H0 ⊦ (((P0 * P1) * P2))(H1 ∪ H0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 24:
⊦ ((P0 * P1))(H) ↔ (∃ H0, H1. H0 ⊥ H1 ∧ H = H0 ∪ H1 ∧ P0(H0) ∧ P1(H1))
Proof step 25:
P0(H1), H1 ⊥ H0, ∃ H2, H1. H2 ⊥ H1 ∧ H0 = H2 ∪ H1 ∧ P1(H2) ∧ P2(H1) ⊦ (((P0 * P1) * P2))(H1 ∪ H0)

Rule argument

spec: <toplevel> name: sep seq: ⊦ ((P0 * P1))(H) ↔ (∃ H0, H1. H0 ⊥ H1 ∧ H = H0 ∪ H1 ∧ P0(H0) ∧ P1(H1)) subst: [H, P1, P0] → [H0, P2, P1] flags: <all paths>
