Sep 10, 2018 at 20:21 comment added Noah Schweber Yes, I'll add that to my answer.
Sep 10, 2018 at 20:20 comment added SSequence @NoahSchweber Alright I will do it when I get enough time. Just one small question though. Should the correct symbol be $\omega^{CK}_{\omega_1+1}$ for what I called $\gamma$ in this question? (and just in case the answer is "no" ... what would the correct symbol be?)
Sep 10, 2018 at 19:31 comment added Noah Schweber I think that your final side question should be asked separately - ORMs are complicated enough that an answer to the main question doesn't really subsume the side question.
Sep 10, 2018 at 18:59 comment added SSequence @NoahSchweber Yes indeed
Sep 10, 2018 at 18:58 comment added Noah Schweber Does "ORM" stand for "ordinal register machine"?
