comment Status of the 196 conjecture?
Aaron: Sorry I missed your comment! That's an exciting idea! Could you possibly state your conjecture more explicitly? Are you trying to give a necessary and sufficient condition for $s(x)$ to be a palindrome?

comment Compactness-like property for universal generalization?
Goldstern: My trouble is figuring out what other relations between the models might be relevant here. (Obviously I'll post if I figure that out.) Unfortunately, I do not understand the part in quotation marks. :-/ (Care to explain more?) $\phi$ does not mention the well-order. Francois: Thanks for the suggestion! I am going to play with it and see if it gets me anywhere.

comment Compactness-like property for universal generalization?
Andres: That's an excellent question, and it shows that what I'm asking for can't be done in general. In my specific problem, $\phi(x)$ has a form which excludes that case. But it seems clear that I haven't asked the right question, because I haven't included enough constraints to yield a solvable problem. I will see if I can repair my question; and in the meantime, thanks for your help!

comment Constructible models of New Foundations?
@Andreas: Thanks; I'll edit the question. I'd like to use the trick you described for eliminating parameters in a proof I'm writing. Is it something you thought of in this thread, and if so may I cite your comments here? Thank you!
