   Format: MarkdownItexI added a sentence about the internal $(\infty, 1)$-topos structure. <a href="https://ncatlab.org/nlab/revision/diff/%28sub%29object+classifier+in+an+%28infinity%2C1%29-topos/44">diff</a>, <a href="https://ncatlab.org/nlab/revision/%28sub%29object+classifier+in+an+%28infinity%2C1%29-topos/44">v44</a>, <a href="https://ncatlab.org/nlab/show/%28sub%29object+classifier+in+an+%28infinity%2C1%29-topos">current</a>

   I added a sentence about the internal $!A = \sum_{E: V} (E \to A}(\infty, 1)$-topos structure.

   Format: MarkdownItexI have fixed that link now. But it's strange: what it took to fix it was to move it into its own line in the source, which shouldn't really affect anything. Hope this is not a sign of many other links being broken now...

   Format: MarkdownItexThanks. We could do with someone explaining what possessing such an internal structure involves.

   Format: MarkdownItexI wonder if it was a transient cache issue and what solved it was simply a re-rendering? I moved it back onto the previous line and it still works. Then I changed it to an intrawiki link rather than an external one, which is even better.

   Format: MarkdownItexOh, thanks for saying that. For some reason that escapes me, I was thinking all along that pointer to anchors does not work in double square bracket links.
