Sadly, Cantor's attic is making an error. This is all I know about Jager's ordinal collapsing functions.


I know it is in [the paper](https://link.springer.com/article/10.1007/BF02007140), but it is not free. I want to know about the ordinal notation from Jager's ordinal collapsing functions.



Can I find the definition of Jager's ordinal collapsing functions?
I thank Carlo Beenakker for the comment.


I can see Jäger's function in [Googology Wiki](https://googology.wikia.org/wiki/J%C3%A4ger%27s_function?oldid=278807), now. This page is the revival of Cantor's Attic.
