comment Continuous function on a compact metric space is uniformly continuous
@ArturoMagidin Actually, just picking the smallest one is not good enough because then the two points might not lie in the same delta ball.

comment Showing the existence of the $\omega_\omega$-th power set of $\omega$
Thanks. So I'll write $G(\langle f_0, f_1, \dots, f_{\alpha}\rangle) := P(f_{\alpha})$ if $\alpha$ is a limit ordinal and $G(\langle f_0, f_1, \dots\rangle) := \bigcup_{\alpha < \lambda}P(f_{\alpha})$ if $\lambda$ is a limit ordinal.

comment Formal proof involving $\varphi( v_k / v_l )$
@CarlMummert The only other axiom involving $\exists$ is $\forall x(\varphi(x) \rightarrow \psi) \rightarrow (\exists x \varphi(x) \rightarrow \psi))$. The axioms are listed in this document starting on page 4.
