Hey all, the group theory thing reminds me a lot of cyclic groups or ideals generated by the value 2. Also equivalence classes (which come up in group theory) can be written with [brackets] but may be confused with <cyclic groups> or (ideals).

The 2;2 notation looks like the notation \mu; \nu that is used for covariant derivatives of tensors in physics. Also 2,2 looks like \mu, \nu that is used for partial derivatives of tensors. And as mentioned above, (2) could be a cyclic subgroup or ideal generated by two or a special case of cycle notation for elements of symmetry groups used to mean an element that keeps 2 fixed. [[Special:Contributions/162.158.62.120|162.158.62.120]] 23:32, 2 May 2022 (UTC)

I second the point about tensors. Maybe you could expand the summation notation slightly. It's common to use index sets or rules underneath large symbols for all sorts of things, like sums, products, direct sums, direct products, unions, intersections, integrals, and much, much more. So here, the large 2 in parentheses represents one of these symbols. Rather than adding or multiplying the elements or whatever, you are twoing them, whatever that means. You are twoing over all values of 2, apparently. It's sort of reminiscent of jokes with punchlines like "for sufficiently large values of 2." There are of course, different 2s out there. Like, there is the von Neumann ordinal 2, the integer 2, the rational number 2, the real number 2, the complex number 2, the residue class of 2 mod 3, etc. All of these may be represented by 2. Perhaps we are indexing over some collection of canonical representations of 2? [[Special:Contributions/172.70.130.161|172.70.130.161]] 00:02, 3 May 2022 (UTC)

Explanation needs something about one of the 2s being cursed. Also, this should be added to the category for cursed stuff (I think it's cursed things, but did not look it up). [[Special:Contributions/172.70.211.72|172.70.211.72]] 01:37, 3 May 2022 (UTC)

::I assumed it was calling us, the people who clear up their mess, "janitors", i.e. menial cleaners/fixer-upperers. But I honestly don't know what dialect/culture uses that (sounds a bit Australian, but not exclusively, and it's a typical and not necessarily derogative kind of word-shortenning that anybody might use) and if they ''do'' mean to call us janitors then... I'm happy to be a janitor. It's a worthwhile occupation, and I consider that an important job that I'll willingly do in the face of such a moron.

:::Noting that the infamous Cursed Chair had not been labelled, yet Curse(d?) Words had, I added the former and took no additional liberties in adding all other cursed things that seemed to lie within that scope (some by in-comic or in-titletext reference, I know) that weren't already included through the Cursed Connectors membership. I web-commented each Catsgory-markuped entry (to varying degrees of directness) in case anybody needs a clue as to why it is added. Obviously I accept any community disagreement on some of the more marginal representative 'items' (words, air, and a <4<sup>th</sup> minus one> thing that is even more conceptual), but that's what a collaborative wiki is for, yes? ;) [[Special:Contributions/172.70.85.177|172.70.85.177]] 21:17, 3 May 2022 (UTC)

The comment about combinatorics, in the section about the "cursed" stuff, uses superscript and subscript 2s.  But that isn't quite correct; they should be stacked rather than one after the other.  It *should* be possible to get the proper display using math mode, which is permitted in the main body of explanation though not in the transcript.  I think it *ought* to be something like "&lt;math&gt;{2}\choose{2}&lt;/math&gt;", but when I try it, I get an error: "Failed to parse (Missing &lt;code&gt;texvc&lt;/code&gt; executable. Please see math/README to configure.)" -- clearly I don't know what I'm doing.  Can someone who's more knowledgeable than I am fix that, please?

:The ideal solution would probably be to use "math" mode to display the symbols.  There are several options: "\choose", "\binom" / "\dbinom" / "\tbinom".  But I don't know how to enable that.  I'm under the impression that when a "math" expression is used in this wiki, the expression is essentially compiled into an image, and I don't know how to make that happen.  If I edit a page with an existing math-mode expression and make any change to the expression, the expression breaks with an error message, as I mention above.
