reserve D for non empty set,
  i,j,k for Nat,
  n,m for Nat,
  r for Real,
  e for real-valued FinSequence;

theorem Th8:
  for D being set, e1 being FinSequence of D holds n |-> e1 is
  FinSequence of D*
proof
  let D be set, e1 be FinSequence of D;
  e1 in D* by FINSEQ_1:def 11;
  hence thesis by FINSEQ_2:63;
end;
