Nuprl Lemma : new_23_sig_rounds_inc
∀Cmd:ValueAllType. ∀notify,propose:Atom List. ∀f:new_23_sig_headers_type{i:l}(Cmd;notify;propose). ∀es:EO+(Message(f)).
∀e1,e2:E. ∀n,round1,round2:ℤ.
((e1 <loc e2)
⇒ round1 ∈ new_23_sig_NewRoundsState(Cmd;notify;propose;f) n(e1)
⇒ round2 ∈ new_23_sig_NewRoundsState(Cmd;notify;propose;f) n(e2)
⇒ (round1 ≤ round2))
