Hi, I am in a bit of a problem. What I have are two sets of numbers $\displaystyle X= \{x_i : x_i = \frac{1}{i} \mbox{ for } i\in [1..\inf)\}$ and $\displaystyle Y= \{y_i : y_i = \frac{1}{i!} \mbox{ for } i\in [1..\inf)\}$ obviously there is 1to1 mapping between them. What i need is to prove it. Any pointers?? Next I know that these are two different sets and the ! is a function connecting them. Given that one is interested in a pairwise distance between elements of two sets: $\displaystyle d(x_i,y_i) =  x_i  y_i $ is there any chance to make any transformation in order to make these distances as small as possible. Am I making any sense?

Transform it in a set theory problem, than apply the transfinite law of induction. {1,1!} ; {2,2!};....{i, i!}, {i+1, ?}
