   Format: MarkdownItexHi, How can I enter a greater-than symbol in a latex expression in an nLab page? When I do it in the usual way I get the error 'unknown character'. 15 minutes of looking at help pages has not enlightened me. Cheers Jamie

   Hi,

   How can I enter a greater-than symbol in a latex expression in an nLab page? When I do it in the usual way I get the error ’unknown character’. 15 minutes of looking at help pages has not enlightened me.

   Format: MarkdownItexThe documentation of how to in the nLab is rather hit and miss. I've sometimes just resorted to finding an example in the nLab or nForum. For your case, the page [[preorder]] contains the text: > A preorder (also sometimes called a quasi-order, especially if one works with $\lt$ instead of $\leq$) ... If you just copy and paste part of that (at least in FIrefox) you get the text: > `with <\lt instead of ≤\leq` which gives the rendering followed by the underlying iTeX. Also, if you want to do tests to figure out how to get some rendering, the nForum is often better than the nLab because it does give previews and you don't have to click `Add your comments` while the nLab requires `Submit` to see the rendering.

   I’ve sometimes just resorted to finding an example in the nLab or nForum.

   For your case, the page preorder contains the text:

   A preorder (also sometimes called a quasi-order, especially if one works with $\lt$ instead of $\leq$) …

   If you just copy and paste part of that (at least in FIrefox) you get the text:

   with <\lt instead of ≤\leq

   which gives the rendering followed by the underlying iTeX.

   Also, if you want to do tests to figure out how to get some rendering, the nForum is often better than the nLab because it does give previews and you don’t have to click Add your comments while the nLab requires Submit to see the rendering.
