Exactly. It does not concern the result, the limit. > The loss, if happened, had to happe at a finite index. Uh no, then we wouldn't have an infinite sequence. It is your perennial failure to conceptualise the infinite as something after every and all finite indices. >>> The reason is that all pairs of the bijection proving same cardinality >>> have infinitely many dark successors which cannot be bijected. >> A bijection which does not biject everything is not a bijection, > So it is!
