: There are a bunch of other regular polyhedra besides the Platonic solids. Most notable are the triangular, square, and hexagonal tilings (which are planar and infinite) and the four Kepler-Poinsot polyedra (which are nonconvex). And there are dozens more if you don't require faces to be planar. [[Special:Contributions/172.70.178.234|172.70.178.234]] 09:44, 27 May 2023 (UTC)

: Some of the proofs of the theorem that there are exactly five platonic solids do not require our minds to "comprehend their shape", because they only rely on their algebrical properties. In fact, the Group theory proof works in any dimension (≥3), despite our minds being very bad at picturing what stuff looks like in higher dimensions. In fact, it's a bit of the opposite: lower dimensions (2 and 3) are "special cases", because all other dimensions have exactly 6 such platonic solids.

I think this is a reference to how the Utah Teapot is nicknamed “the sixth Platonic solid” due to its presence beside real Platonic solids in demonstrations of 33D rendering. [[Special:Contributions/172.68.118.133|172.68.118.133]] 08:52, 27 May 2023 (UTC)

:...yeah, but you need to render that 33D shape on a proper 32D monitor, ideally, because even on a 31D monitor the two different forced perspectives/projections you need to collapse the extra dimensions down tend to look confusing.

:: Thanks, that predates my claim in https://arxiv.org/abs/2103.00090, so I won’t claim priority:
 
::: ‘By this conception, the claim that there is a Russell Set is simply wishful thinking, analogous to wanting the phrase “sixth Platonic solid” to have a referent, while not actually intuiting which shape this might be.’

Should we think about Jorb, perhaps, as "J orb," which might lead us to think about (''i'',''j'') coordinates, i.e. notational systems where ''j'' is the square root of minus 1? (blah blah engineering vs. mathematics, what does ''i'' mean, &c., &c., &c.) Maybe not! [[User:JohnHawkinson|JohnHawkinson]] ([[User talk:JohnHawkinson|talk]]) 10:41, 27 May 2023 (UTC)

I feel that there's a joke missing here, especially with the LOTR connection made in the alt-text. After all, Plato might have gifted the solids to the mathematicians, but thanks to Gary Gygax, it was the gamers who found a use for them....

I kind of feel sorry for the platonic solids. Condemned to the friend zone for eternity; or at least until the end of this universe.

Also the Gömböc comes to mind from the name, the shape and the novelty of Jorb.

: Added link to "{{w|Gömböc}}", as that is immediately what I thought of when seeing this comic. Randall's Jorb looks designed to have Gomboc-like properties: if starting on the long thin facet seen on the top edge, it would be gently pulled down by the large round egg-like "end" and then presumably roll onto one side or the other i.e. rotating around its long axis until reaching the position shown. If the Jorb were indeed a mono-monostatic shape, then like the known Gömböc design it would be a "polyhedron" with one (albeit curved) "facet", and like the Platonic solids it can rest on any one of its facets, trivially true as there is only one facet.

So, I think this explanation is under-focused on the actual joke. The core humor here is the idea that "Platonic Solid" means "Solids Plato made" and not regular polyhedra at all. "Mathmetitions long believed there were five platonic solids, all regular polyhedra" So the jorb is explicitly a platonic solid that is not a regular polyhedra. Our explanation should point out then, things like the fact that the platonic solids predate Plato.
 
 
There is no doubt that the cube is the most common, but today a strange force made a lot of tetrahedron objects appear. This happens every year.

:I'd like the answer to two questions:
 
:# What is CG even talking about?
 
:# What is the person who keeps removing CG's comment even complaining about? (Something about Cultural Misappropriation, but ''which'' culture(s)?)
 
:...maybe the answer to one will answer the other, but I've a feeling they're  entirely unconnected. Perhaps one (or both?) just trolling. Yet, unless 7/7 is International Dungeons&Dragons™ Day, or something, neither even close to what I'm imagining it's about.

'''Stop your games'''. And they clearly ''are'' games, as we already know about the historic link between the [https://www.explainxkcd.com/wiki/index.php?title=Talk:2781:_The_Six_Platonic_Solids&diff=next&oldid=317682 .XXX and CG-styled accounts], which you (singular/plural, I don't care) have now used to 'edit war between yoursel(f/ves)'. I don't generally care if the comment is there (whatever it even refers to, but with no obvious 'illegality') or not, but useless reverts/de-reverts/re-reveets/etc should not be tolerated.

It does kinda feel like you all are oblivious to the fact that lots of people won't have a blind clue what any of this actually means. Can someone please translate the explanation from mathematical gibberish to language a lay-imbecile such as myself could understand? What actually *is* a platonic solid might be somewhere to start, in words like 'edges' and 'faces', instead of this 'convexual polyhydra' nonsense... Thanks. [[Special:Contributions/141.101.99.145|141.101.99.145]] 09:28, 23 January 2024 (UTC)
 
:It's all there in the links. And nobody says "convexual polyhydra" on the page, except you.
 
:But... Take a regular polygon (...as in a "flat shape that has equal angles/side-lengths and no internal angles"...) join it up with other (identical) polygons to create a regular ''3D'' shape. The Platonic solids are the full set of these that aren't: a) flat, an infinite plane, b) angled both inwards and outwards, c) self-crossing its surfaces, d) leaves gaps, e) have different-looking corners, ....etc.
 
:It can be shown that (given the above restrictions): a square can be used only to make a cube; a triangle can make a tetrahedron (triangular-based pyramid), an octahedron (two square-based pyramids stuck base-to-base) or an icosahedron (a twenty-sided solid); a pentagon can make a dodecahedron (a twelve-sided solid); no other combinations are possible. Hexagons will tile infinitly (or create a flat 'double-sided' free-floating hexagonal plate) heptagons and more won't even tile. There are thus five of these 'basic' regular solids, described by/ascribed to Plato, as seen (discounting the jorb).
 
:Further 'regular' shapes exist if you undo some of the restrictions (infinite sheets, alternating in-and-out angles, using regular self-crossing shapes and/or allowing the shapes to cross each other whilst forming the solid, etc... e.g. for which someone else recently added links to the additional set of 'stellated' regular polyhedra). Or abandon Euclidean space/expand beyond three dimensions (both of which make Platonic solids no longer fully valid, at the same time). And if you consider "regular convex polyhedra" beyond you, at this point where you've already seen links to a potential wikiwalk to fill in gaps in your knowledge about what these terms mean, then I'm not sure what more I can say. Either here or in the main Explanation. Not without hand-holding you through points that I learnt in maths lessons when I was no more than 11 (and probably already knew, at least in parts). Can't account for current practice, or the localised curriculum that you were taught, of course, but then a 'refresher' or post-education remedial 'filler' lesson isn't going to be possible just through a paragraph or two of blind monologue. Check the links, and ask more specific questions than just not understanding any of it. [[Special:Contributions/172.71.178.66|172.71.178.66]] 10:24, 23 January 2024 (UTC)
