For any ordinal alpha, one may consider the set of all sequences of decimal digits of length alpha. However, if you make the requirement that the set be countable, then the set of alpha for which this is possible is the set of all finite ordinals. This set has no maximum element. Its least upper bound is omega but omega is not a member of the set. There is no reason why this set should have to contain its own least upper bound.

You are reaching. What is false? Y = log (x) or The list is infinite Herc

Why do your questions so often come out garbled? However, > If you listed digit permutations in an infinite list You must mean permutations of an infinite number of digits, otherwise the list couldn't be infinite, but since there's a requirement to list them, the listed permutations must be a subset of the set of all the permutations of the infinite number of digits, since the full set is uncountable, and therefore incapable of being listed. > what is the max digit width that all permutations > could be calculated? God only knows what that means. Sylvia. |
