That is the most ridiculous nonsense that is inherent in matheology,

but, of course, it is required to maintain it. If there is any

meaningful limit of a sequence of sets, then this limit is a set and

as such has a cardinality. If both diverge, then we have the proof

that the limit set is not a meaningful notion.

Nevertheless, I did not use this sover fact in order to show you, that

not even nonsense is sufficient to maintain set theory.

This is the improper analytical limit L of the sequence of numbers.

This are real numbers, in the opinion of some cranks like Greinacher

they differ from cardinals. You seem to be of different opinion. By

the way it is astonishing if not surprising how many different

opinions matheologians entertain.

Perhaps that would be possible in set theory, but not in analysis. In

analysis we have the set of digits of the limit L and we have the set

of indexes of these digits. The set of indexes is 1 + the decadic

logarithm of L. Never heard about that fact? But even if you don't

know, be sure every mathematician knows.
