[MO] Is there a tetration for infinite cardinalities? (Question in MO)
#8
Doner and Tarski can not define exp^[1/2](w) and its cardinality , right ?

Do Doner and Tarski give a different answer to 2^^w ?

I still challenge to give exp^[1/2](w) even under the assumption that ZFC is good.

Sorry for going a bit offtopic.
Guess I have emotional Luggage concerning this.

Im not 100% constructivist for clarity.

regards
