Proof step 71 from proof aux-known (previous step)

rs1 ∩ rs0 = ∅, R[rs0, f, g], a1[r => o](mk(rs1, f, g(r; a1))) ⊦ g(r)[r => o][rs1, f, g], (g(r)[r => o] * R)[rs1 ∪ rs0, f, g], r ∈ rs0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 72:
⊦ a[P](mk(rs, f, g)) ↔ P(mk(rs, f)) ∧ (∀ r. r ∈ rs → g(r) = a)
Proof step 73:
rs1 ∩ rs0 = ∅, ((r => o))(mk(rs1, f)), R[rs0, f, g], ∀ r0. r0 ∈ rs1 → g(r; a1)(r0) = a1 ⊦ (g(r)[r => o] * R)[rs1 ∪ rs0, f, g], g(r)[r => o][rs1, f, g], r ∈ rs0

Rule argument
