# Can the continuum $\mathfrak c$ be a limit cardinal?

Can the continuum $\mathfrak c$ be a limit cardinal?

Thanks for any help!

According to Wiki, I think there are at least two notions of limit cardinals. $\mathfrak c$ seems to be reachable by taking the power set of $\aleph_0$, but not by successor operation without the continuum hypothesis. –  Tunococ Sep 9 '13 at 1:02

Yes. The only restriction is that $\mathfrak{c}$ must be a cardinal of uncountable cofinality. So $\mathfrak{c}$ can be $\aleph_{\omega_1}$, but not $\aleph_\omega$.
