# Misplaced backslashes

I left a comment at Strict ordering on natural numbers but as you can see it says "Misplaced \\". I'm no more allowed to edit it myself, I don't know why. Can someone correct it please? Thanks.

Fixed.

Markdown in comments use a different set of rules than Markdown in posts. In particular, \{ will not be converted to { in comments, so \\{\\emptyset\\} will be left as-is. It is incorrect to place a \\ there in LaTeX, thus the error.

• Is there any good reference on the version of markdown in comments vs. posts? Why the incompatibility? – Bill Dubuque Sep 28 '10 at 18:13
• @Bill: it seems like comments are parsed with regex in real time, instead of storing the parsed HTML, so some rules are restricted to save resource. There is no good reference except by experimenting. ( :( ) – kennytm Sep 28 '10 at 19:24
• Thanks, that useful to know to help understand the design compromises. – Bill Dubuque Sep 29 '10 at 0:16
