摘要 | For a set x, let S(x) be the set of all permutations of x. We prove by the method of permutation models that the following statements are consistent with ZF: (1) There is an infinite set x such that vertical bar p(x)vertical bar < vertical bar S(x)vertical bar < vertical bar seq(1-1)(x)vertical bar < vertical bar seq(x)vertical bar, where p(x) is the power set of x, seq(x) is the set of all finite sequences of elements of x, and seq(1)-(1()x) is the set of all finite sequences of elements of x without repetition. (2) There is a Dedekind infinite set x such that vertical bar S(x)vertical bar < vertical bar[x](3)vertical bar and such that there exists a surjection from x onto S(x). (3) There is an infinite set x such that there is a finite-to-one function from S(x) into x. |
