I recognized this Question as duplicate to one with square brackets in its title (unsurprisingly, since the Q is about irreducible polynomials over $\mathbb{Z}_2$).
The auto link from my vote-to-close (as "possible" duplicate) doesn't format correctly, and despite a couple of tries at a manual fix, no joy.
The problem appears to be that including square brackets inside the MathJax link text (enclosed by square brackets) confuses the link parsing mechanism.
I'm sure the naked URL is usable as is, but I don't recall having this problem before. According to this similar 2011 report, the "bug" was supposed to be "fixed in the next build" (and subsequently marked status-completed
).
So for now I'm tagging this as a bug report as well.
Added: Based on experiments (see Comments below), this quirk is due to an interaction between MarkDown and MathJax. That is, the fix that resulted in status-completed
items in 2011 involves escaping square brackets inside link text with backslashes. However if the square brackets also happen to be inside MathJax (dollar-sign) delimiters, that backslash escaping doesn't work, breaking both the MarkDown link text and the MathJax formula.

so that they produce[

(and also add them as valid delimiters so that they work with\left

). That would not be difficult, but would require some additional custom MathJax configuration on these sites. $\endgroup$\newcommand
