WebSince there is a trivial canonical bijection between binary sequences and the power set of natural numbers, this can easily be modified to a bijection from reals to the power set of natural numbers. We say that a binary sequence has an infinite tail iff from some term onwards all terms in the sequence are 0s or all are 1s.

WebSep 27, 2024 · A little more work with functions (see the exercises) can show that the set of all real numbers is the same size as the set of all the reals between zero and 1, and so the reals, which contain the natural numbers, must be a bigger infinite set. The technical term for the size of an infinite set is its “cardinality.”
