WebApr 23, 2012 · If P is a proposition true for "all but finitely many" elements in a universe U, then the set of elements for which P is false is finite. Which part of that is confusing to people? It's exactly what it says. All but finitely many primes are odd. All but finitely many natural numbers are greater than 42. The set of exceptions is finite.

WebDoes P have finitely or infinitely many elements? If P is finite, how many elements does it have? Question: Let P be the set of all prime numbers p such that 4p2+1 and 6p2+1 are also prime. Any proper subset of a finite set S is finite and has fewer elements than S itself. As a consequence, there cannot exist a bijection between a finite set S and a proper subset of S. Any set with this property is called Dedekind-finite. Using the standard ZFC axioms for set theory, every Dedekind-finite set is also finite, but this implication cannot be proved in ZF (Zermelo–Fraenkel axioms without the axiom of choice) alone. The axiom of countable choice, a weak version of the axiom …
