| Sep 7, 2017 at 14:38 | comment | added | Joel David Hamkins | It was my pleasure. For your question 4, I seem to recall some results that one can have quite a lot of class cardinalities, but I don't remember how to achieve this. | |
| Sep 7, 2017 at 7:29 | comment | added | Gérard Lang | Dear J. D. Hamkins, let me thank you very much. So we now know everything on the possible injections between the four distinct proper Cardinal levels V*, P(On)*,W* and On*, that linearly ordered by surjection. | |
