Oh, thank you. So the article just threw in Continuum Hypothesis because different infinities 'n stuff. But what is confusing to me is that the article suggested p and t are defined as collections of subsets of the natural numbers. The power set of the natural numbers has the same cardinality as the reals, right? Since p and t are both subsets of this power set, they must have cardinalities below the cardinality of the reals.
