    Quick cardinality question

    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 \lim_{n \rightarrow \infty} 2^n = 2^{\aleph_0}?

    What does \lim\limits_{n\rightarrow\infty} here means?

    No。 \lim_{n \to \infty}2^n=\aleph_0<2^{\aleph_0}=c
