| Apr 26, 2022 at 14:04 | comment | added | Andreas Blass | In the first of the two exercises, it would be better not to use $\alpha$ for two different things. | |
| Apr 26, 2022 at 14:03 | comment | added | Andreas Blass | @AsafKaragila The implicit assumption includes "of uncountable cofinality", and that's definitely a constraint on $T$, since the ordinals of cofinality $\omega$ form a stationary set. | |
| Apr 26, 2022 at 8:28 | comment | added | Asaf Karagila♦ | Just a small remark, you don't need to "implicitly assume almost all ordinals in $T$ are limit ordinals", since it is true that almost all ordinals are limit ordinals. | |
