Nuprl Lemma : new_23_sig_quorum_fseg
∀Cmd:ValueAllType. ∀notify,propose:Atom List. ∀f:new_23_sig_headers_type{i:l}(Cmd;notify;propose). ∀es:EO+(Message(f)).
∀e1,e2:E. ∀ni:ℤ × ℤ. ∀zh,z:Cmd List × (Id List).
((e1 <loc e2)
⇒ zh ∈ new_23_sig_QuorumState(Cmd;notify;propose;f) ni(e1)
⇒ z ∈ new_23_sig_QuorumState(Cmd;notify;propose;f) ni(e2)
⇒ let cmds1,locs1 = zh
in let cmds2,locs2 = z
in fseg(Cmd;cmds1;cmds2) ∧ fseg(Id;locs1;locs2))
