theorem Th4:
  for S being non void Circuit-like non empty ManySortedSign for
  A being non-empty Circuit of S for s being State of A, n being Element of NAT
  st Following(s,n) is stable holds Result s = Following(s, n)
proof
  let S be non void Circuit-like non empty ManySortedSign;
  let A be non-empty Circuit of S;
  let s be State of A, n be Element of NAT;
  assume
A1: Following(s,n) is stable;
  then s is stabilizing;
  hence thesis by A1,Def4;
end;
