Description: The sequence , , and forms a chain of proper subsets. In each case the proper subset relationship is shown by demonstrating a number that belongs to one set but not the other. We show that zero belongs to but not and minus one belongs to but not . This theorem refines the chain of proper subsets nthruc 14981. (Contributed by NM, 9-May-2004.) |
