I'm going to start a thread in the Chat section about cardinality (maybe, we'll see), but would like clarification on one thing first... Does $\displaystyle \lim_{n \rightarrow \infty} 2^n = 2^{\aleph_0}$?

Hi What does $\displaystyle \lim\limits_{n\rightarrow\infty}$ here means?
No。$\displaystyle \lim_{n \to \infty}2^n=\aleph_0<2^{\aleph_0}=c$
