comment Determine whether two primitive recursive functions are equal
How can we be sure the extra assumption (that the indices we are comparing are of primitive recursive functions) doesn't allow us to solve this?

comment A question about cardinal number.
Just make sure to choose a linear order with no maximal element.

comment What sets satisfy $V = V^V$?
Ah, thanks, will keep in mind. I'm used to $V$ being used for arbitrary sets, but that's probably due to my language of education (Dutch).

comment What sets satisfy $V = V^V$?
Could you clarify what you mean with "the universe"? I simply meant a set $V$ such that $V = V^V$; Alex has already pointed out that there's only one such set, though.

Good point. I guess that gives me my set then, heh. I was hoping for something bigger, didn't think about the cardinalities issue. :)
