   Format: MarkdownItexbecause I needed the link I have created a stub [[(2,1)-site]]. I define it there as an [[(infinity,1)-site]] whose underlying category is a [[(2,1)-category]]. Don't have the leisure right now to check that this is also a [[2-site]] whose underlying 2-category is a $(2,1)$-category, as hopefully it is

   Format: MarkdownItexI have fixed it. In the original sentence one of the $\infty$-s should have been a 2. But there is also a statement with the $\infty$ in there about 2-locality. I added that, too.
