theorem Th14:
  for S being non void Circuit-like non empty ManySortedSign for
  A being non-empty Circuit of S, s being State of A holds Following(s,1) =
  Following s
proof
  let S be non void Circuit-like non empty ManySortedSign;
  let A be non-empty Circuit of S, s be State of A;
  0+1 = 1;
  hence Following(s,1) = Following Following(s,0) by Th12
    .= Following s by Th11;
end;
