Proof step 54 from proof write-known (previous step)

rs1 ∩ rs0 = ∅, R[rs0, f, g], a[r => o0](mk(rs1, f, g)), r ∈ rs0 ⊦ # rs0 = 0, rs0 = ∅, R[rs0, f(r; o1), g], (a[r => o1] * R)[rs1 ∪ rs0, f(r; o1), g] ∧ f(r) = o0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 55:
⊦ a[P](mk(rs, f, g)) ↔ P(mk(rs, f)) ∧ (∀ r. r ∈ rs → g(r) = a)
Proof step 56:
rs1 ∩ rs0 = ∅, ((r => o0))(mk(rs1, f)), R[rs0, f, g], r ∈ rs0, ∀ r. r ∈ rs1 → g(r) = a ⊦ # rs0 = 0, rs0 = ∅, R[rs0, f(r; o1), g], (a[r => o1] * R)[rs1 ∪ rs0, f(r; o1), g] ∧ f(r) = o0
