    Thanks!

    This overlaps a bit with the previously existing entry dense subsite. I have cross-linked the two now.

    (To see the changes, you may have to make sure to go to comparison lemma (lower case) … the cache bug seems to be still in effect after all.)

    The use of the term dense subcategory here is different from the two notions mentioned on that page, right?

    Yes, dense subsites are not in general dense subcategory inclusions of sites. The two uses of “dense” are unrelated (one is combinatorial, the other is topological, in a way).

    I have added a corresponding warning to both entries.

    Add reference to (∞,1)-comparison lemma (itself TBD shortly).

    Cross-linked to “dense subsite”.
