theorem Th63:
  for T being non empty non void reflexive transitive
  TAS-structure for t being type of T holds {} the adjectives of T
  is_properly_applicable_to t
proof
  let T be non empty non void reflexive transitive TAS-structure;
  let t be type of T;
  take s = <*> the adjectives of T;
  thus rng s = {} the adjectives of T;
  let i be Nat;
  thus thesis;
end;
