The FAQ article How does cardinality work? contains a typo. The last sentence of the section titled The rational numbers are countable states

So by applying Cantor-Bernstein-Schroder, we have that the positive integers are countable.
The underlined phrase should be replaced by "rational numbers."

Is there a button to report the Library item? That would be the quickest way to get it fixed, I think.

Well, when you press the Report button it states

Note: This is ONLY to be used to report spam, advertising messages, problematic (harassment, fighting, or rude) and unappropriated posts.
so I didn't think it was appropriate to report a typo that way. I did send Greg Bernhardt (the author of the article) a PM about this matter about a month ago (June 27), but no reply.

It's okay to report important typos with the Report button. Tell 'em berkeman sent you

Greg is the site owner, and in some places his name used by default - it doesn't necessarily mean he is the author. You must hit one of these moments when he was occupied with something else, as usually he will just forward such information to staff members well versed in math.
