がウソ
なぜか？
＞N = { 0,1,2,3,4,・・}として、この集合Nの最外側の{}を外して、元を並べると
＞自然数の列 0,1,2,3,4,・・ となる
が、列 0,1,2,3,4,・・の最右の元は存在しない！
これが理由

Axiom of infinity
Interpretation and consequences
This axiom is closely related to the von Neumann construction of the natural numbers in set theory, in which the successor of x is defined as x ∪ {x}. If x is a set, then it follows from the other axioms of set theory that this successor is also a uniquely defined set.
