Nuprl Lemma : State-comb-invariant-sv
∀[Info,A,S:Type]. ∀[P:S ─→ ℙ].
∀init:Id ─→ bag(S). ∀f:A ─→ S ─→ S. ∀X:EClass(A). ∀es:EO+(Info). ∀e:E. ∀v:S.

⇒ single-valued-classrel(es;X;A)
⇒ (∀s:S. (s ↓∈ init loc(e) ⇒ P[s]))
⇒ (∀a:A. ∀e':E. (e' ≤loc e ⇒ a ∈ X(e') ⇒ (∀s:S. (s ∈ Memory-class(f;init;X)(e') ⇒ P[s] ⇒ P[f a s]))))
