Proof step 13 from proof map-putex (previous step)

((r => o * P))(H) ⊦ ((r => o1 * P))(H[r, o1])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 14:
⊦ ((P0 * P1))(H) ↔ (∃ H0, H1. H0 ⊥ H1 ∧ H = H0 ∪ H1 ∧ P0(H0) ∧ P1(H1))
Proof step 15:
∃ H0, H1. H0 ⊥ H1 ∧ H = H0 ∪ H1 ∧ ((r => o))(H0) ∧ P(H1) ⊦ ((r => o1 * P))(H[r, o1])

Rule argument

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