theorem Th26:
  for m being CR_Sequence, c being CR_coefficients of m, i being
  Nat st i in dom c holds c.i,1 are_congruent_mod m.i
proof
  let m be CR_Sequence, c be CR_coefficients of m, i be Nat;
  assume i in dom c;
  then
  ex s being Integer, mm being Integer st mm = Product(m) / m.i & s * mm
  , 1 are_congruent_mod m.i & c.i = s * (Product(m) / m.i) by Def4;
  hence thesis;
end;
