This is all still Euclidean though, which Eldritch horror is clearly described as not being. Allowing for non-Euclidean curved space would presumably pretty easily allow for infinite regular polyhedra, stuff like angles adding up to 360 degrees doesn't apply anymore so you could have a septagon sided shape etc.

But there probably isn't a way to create infinitely many classes of *regular* polyhedra that are unique.

to explain 5/2: 1. imagine you have five dots in a circle 2. connect those dots via lines to make a shape 3. make note of how many dots you move around the perimeter each time you connect a dot (Make sure these are equal) 4a. if you move 1 dot per line, you end up making a pentagon, therefore it would be 5/1, but you dont have to write the 1, as it is understood by default. 4b. if you move 2 dots per line, you end up making a pentagram (5 pointed star), therefore it would be 5/2 4c. if you move 3 dots per ling, you still end up making the same pentagram, just the other way around, so it would still be 5/2 another more complicated example: There are multiple ways to make an 8 pointed star, and the schlaffle symbol allows us to distinguish between them. 1.have 8 dots in a circle 2.connect those dots in the same manner as the 5 dots 3. notice that now you have more choices on how many spaces you can go and make different polygrams (stars) 4a. 1 dot gives you an octogon, 8 4b. 2 dots give you a square octogram (an 8 pointed star made by stacking squares), 8/2 4c. 3 dots give you a different octogram (this one can be drawn withut lifting your pen), 8/3 4d. 4 dots give you an 8 pointed asterisk (the * symbol but with 8 points instead of 5), 8/4 4e. 5 dots makes 8/3 in the other direction. now hopefully, you understand a little more about schlaffle symbols.

Thank you very much about this comment. I believe there was a vihart video I watched that made it easier to understand this comment. She didn’t use any notation but she was creating every type of stars including 5/1 (that is a pentagon I don’t remember whether she called it a star in the video or not), 7/2 or 6/3 or 6/2

So 8/2 results in pairs of edges that completely overlap. Jan Misali was explicitly not allowing overlapping edges or faces or vertices, but if you did allow them, it would surely give infinite regular polyhedra.

Yeah but it would be reasonable to limit it to finite ones, constructed with flat polygons. This would include the star polyhedra, but exclude: the petrials (cause those ain't flat polygon faces) the tilings (they're infinite) and the petrie coxeter polyhedra (which are both infinite and don't have flat polygonal faces) The restriction removed from the platonic solids is just that edges are now allowed to intersect.

why not just define "platonic polytopes" as being closed, finite and orientable and then have them be: vertex-transitive edge-transitive face-transitive cell-transitive etc. but more specifically, we can define an n-dimensional analogue of vertices/edges/faces/cells/etc recursively by only allowing "platonic polytopes" as counting, essentially meaning that a platonic polytope must have its vertices/edges/faces/cells/etc made of platonic polytopes in order to count as a platonic polytope. then, **i think**, we get the intuitive notion of the generalisation of a platonic solid.

@@UnordEntertainment That's essentially what they already do. It's part of the definition of regularity. Note that even the abstract polyhedra mentioned in this video are composed entirely of regular polygons. Similarly, regular polychora are composed entirely of regular polyhedra. The general rule is that they have to have every possible symmetry. They have to be transitive on every flag (vertex, edge, face, facet, etc.). If we further require them to be closed (thus finite) and convex (thus not self-intersecting), we get the usual list (up to Petrie duality).

One of the restrictions you chose to include was that two points connected by line segments doesn't count as a polygon. That's a sensible exclusion, but that is actually my favorite shape, the digon. It's not very interesting in a plane by itself so explicitly excluding it for this video is a good idea, but on a sphere it's a really important shape called a lune, think of it as the boundary on a sphere of an orange wedge. But way more importantly, a digonal antiprism is a tetrahedron! it's so cool! a totally different way of constructing a tetrahedron. A tetrahedron is two line segments, degenerate digons, rotated 90° and connected vertex to vertex. If you allow the digon there's also at least 1 new regular polyhedron, The Apeirogonal Hosohedron, basically a tiling of the plane by infinitely long rectangles, or stripes. This is my favorite video of your channel and it singlehandedly reignited my interest in geometry and topology.

Watch some of AntVenom's videos on the true structure of Minecraft's farlands. It varies by version and edition but generally the region that has normal minecraft world generation and physics is less than a trillionth of a trillionth or a trillionth of the area one can hypothetically visit. From what I recall of a fairly old version: most of it has no ground at all, only clouds, and normal motion is impossible because position is too discretised for you to move, so you can only teleport. Most of the remainder is corner farlands that have intangible ground. Most of the remainder is edge farlands that are similar. Most of the rest is corner farlands that are at least tangible. Most of the rest is edge farlands that are similar. Most of the rest is normal terrain with noticeably jerky movement. The tiny remaining part is the "normal" minecraft world.

As a mathematician, I can not thank you enough for doing something like this. I'm no expert on geometry, but regular polyhedron and polychora for 4d are some of the things I find the most interesting. Have not finished it yet but just the act of making it is wonderful. Edit #1: Not done but when you introduce stellated dodecahedrons, you say they are called "stellated" because they are made from stars but this is technically inaccurate. Something being stellated is weirder than that and I am not an expert on the subject but look at en.wikipedia.org/wiki/Stellation. Edit #2: It is immediatly noted that another way of thinking about it is the formal Stellation thing but so nvm I guess.

I always assumed that stellation referred to the fact they looked like stars; a pentagram looks like a pentagon with spikes instead of edges - similarly the faces of a dodecahedron or icosahedron were replaced with pyramids. Each face being uniformly augmented to a point. For that reason i assumed they weren't regular, but i suppose being thinly defined as stars for faces caught me off guard. They are however "Stellated" because they look like stars - a pentagram is technically a stellated pentagram

I'm just upset that nobody else is objecting to his use of skew polygons here, which are not actual polygons. Polygons are in fact defined as being 2 dimensional. I had other objections, but that's where I started shouting at my screen.

@signisot5264 4 жыл бұрын
Theoretically, if you define a regular polygon as any polygon with edges of uniform length which share the property of edge and vertex transitivity where each vertex connects to two edges and each edge to two vertexes (a moderately restrictive definition, but definitely not what we think of as regular polygons) then by all means, skew polygons are entirely valid. I appreciate the fact that Petrials still have uniform, transitive faces, edges, and vertices, and are rather simple if you understand them

@@signisot5264 but the technical definition of the polygon, in Euclidean space, states that it is a two dimensional figure. You can't have a polygon which extends into a 3rd dimension any more than you could have a polygon with a curved edge, or a square with 120 degree interior angles.

Leo Staley, it all comes down to the definition and, if we’re willing to change the definition of a polygon in exchange for not changing the definition of a regular polyhedra, then we may as well throw our standard definition of “regular polygon” out the window. Since most of these are abstract or infinite anyways, physically it doesn’t matter, but I’ve actually taken inspiration from the petrial cube as the solution to a problem I was having (coding something) so, as long as it’s a useful abstraction, I’ll support it. Wether or not we call it regular... (Edited cause I used the wrong words for some things, whoops)

Oh boy, yes Vertices.... I got my BS in Animation (2D&3D) & wen we model for animation we map our polygons, sometimes for repeatable textures- they do breakdown to triangles, but usually use 4 sided faces to make nice mappable squares/quads. 5 is a no no because of artifact/shading probs and such when animated. But holy heck- if you're using polygons & make a mistake early you're in for it. (Rudimentary comment don't come @ me w/aCtuAlLty ... I'm echoing the struggle for perky noobies.)

Thankfully I only had to invent some; say, "Petrial halved mucube dual" needs four words "Petrial" (a proper noun), "halved" (translated), "mucube" (mu- invented) and "dual" (existing) but only one word has to be invented and reused. And no, the only thing I have is a master's degree in computer science, which has a crossover with discrete mathematics but that's about all. An ability to parse academic papers did help, though.
