theorem Th16:
  for S being one-gate ManySortedSign holds InnerVertices S = { Output S}
proof
  let S be one-gate ManySortedSign;
  consider X being non empty finite set, n being Element of NAT, p being
  FinSeqLen of n, f being Function of n-tuples_on X,X such that
A1: S = 1GateCircStr(p,f) by Def6;
  Output S = [p,f] by A1,Th15;
  hence thesis by A1,CIRCCOMB:42;
end;
