@user1729 yes :) that's what I was asking
Dec 12, 2021 19:35
:/ That's always hard to predict on the Math SE's @Shaun

thank you @Wolgwang :) you're extremely helpful

maybe it's not a clarity issue and the reason given was overly braud
Dec 11, 2021 15:17
the room is empty
Dec 11, 2021 15:15
they might send me back here :-P
Dec 11, 2021 15:15
I could go to that room and ask, thanks.
Dec 11, 2021 15:14
you like geometry :) I like very visual stuff like Geometry, Abstract Polytopes and Graph theory too :)
Dec 11, 2021 15:11
that's the one :) chears for having a look
Dec 11, 2021 15:10
I'm not sure what clarification could apply, I wish the reason was more specific.
Dec 11, 2021 15:09
there are many better episodes than that one
Dec 11, 2021 15:08
I'm having difficulty clarifying a closed question.

Hey :)

Do similar/nearby combinatoric sequences accelerate in the same way? Can various sequences be taken together to meaningfully produce a higher resolution (more continuous) sequence?
Mar 9, 2020 22:51
Hey Ted, do you like Polyhedra, Polytopes, Graphs?
Mar 9, 2020 22:44
Monty Hill like problems are much harder than Monty Carlo or Monty Python ones :/
Mar 8, 2020 14:55
better or worse that with few dimensions?
Mar 8, 2020 14:54
How well are arbitrary_paths and/or random_walks aproximated in higher dimensional flat space?
Mar 6, 2020 01:58
I guess it cannot work forever as there is a maximum (monster) size of finite group, but maybe smaller ones do.
Mar 6, 2020 01:46
Maybe a family of groups can be made out of 90 degree axially aligned rotations of (1, 1, 1, …) in N dimensional or Hilbert space like so.

e = 1

e = 1, 1
a = 1, -1
a^2 = -1, -1
a^3 = -1, 1

e = ab = a^4 = b^4 = c^4 = 1, 1, 1
a = 1, -1, 1
a^2 = -1, -1, 1
a^3 = -1, 1, 1
b = c = 1, 1, -1
b^2 = 1, -1, -1
b^3 = 1, -1, 1
ba = 1, -1, -1
c^2 = aabb = baaa = caaa = -1, 1, -1
aabbb = -1, -1, -1

etc…

The inclusion of "c" doesn't seem promising.

nvm

seems to consist of one finite and various infinite trees, every graph that's just one cycle, the triangle grid, square grid, and hexagonal grid, and just one more that I can find where each vertex neighbours four triangles and a rhombus
Feb 16, 2020 21:03
unit distance planar vertex transitive simple graphs, with an embedding where faces are convex
Oct 27, 2019 11:58
Well, it should work 🤷🏻‍♂️, I'm looking for if it already has a name.
Oct 27, 2019 11:29
I've not seen this notation, it's a bit of a mouthful, and probably allows all sorts of figures not possible geometrically, but it is very general and kind of what I am looking for at the moment.
Oct 27, 2019 11:28
I'm thinking a schläfi notation tetrahedron {3, 3}, or a cubic honeycomb {4, 3, 4} (note thease don't need to be able to fit into flat space) and in the archamedian notation truncated cube {8, 8, 3}. How about a (probably hyperbolic) honeycomb made of lets with three truncated cubes two non adjacent octahedrons around each edge notated as something like {{8, 8, 3}, {8, 8, 3}, {3, 3, 3, 3}, {8, 8, 3}, {3, 3, 3, 3}}.
Oct 27, 2019 11:10
Is anyone any good with schläfli symbols and unform (rather than just regular) polytopes such as archimedean solids?
Oct 27, 2019 11:09
Hello
May 10, 2019 15:26
But it's higher level than me, but not so much that I get nothing from it.
May 10, 2019 15:25
:) No affiliation here, just both found it and found it awesome lately. Lots of interesting stuff.

Somone tell me if this is just too ridiculous before I leave the answer there :-P
Dec 4, 2018 13:59
I tried to relate this to functions like in the original 1D case, but I wasn't able.

A: Extenstion of Intermediate Value Theorem.

alan2hereI expect such a theorem to already exist, for if it doesn't, I posit the Intermediate Slice Theorem. It makes statements analogous to the intermediate value theorem. $d$ is a member of N. P = $\mathbb{R}^{d}$ Q is an $\mathbb{R}^{d - 1}$ dimensional line in P. A 0 dimensional line is a point,...

Dec 4, 2018 13:56
What do you think of my theorem?
Dec 4, 2018 12:40
I like the / \ basic program posted above :) It's very elegant.
Dec 4, 2018 12:36
I might make a question now :)
Dec 4, 2018 12:34
But maybe it all works in wilder examples, such as for (nodes and edges) graphs too, for example.
Dec 4, 2018 12:33
I assume that more intricate formulations based on the "intermediate value theorem" such as the I'm hungry and want a ham sandwich problem, table and planet examples must work in R and R<sup>2</sup>. And presumably therefore in vectors. And even more presumably in tensors and in the complex plane.
Dec 4, 2018 12:28
thank you :)
Dec 4, 2018 12:27
@AkivaWeinberger There must be a name for this property, it's bassicly the same property in all my examples.
Dec 4, 2018 12:26
@Adam "equivalence classes" is a more general idea like this, where a set is divided in it's entirety into smaller non-overlapping sets
Dec 4, 2018 12:24
The convex shape one is called the ham sandwich problem :) A great name. All the shapes can even be different from each other.
Dec 4, 2018 12:22
thanks, I'll fix that mistake
Dec 4, 2018 12:19
2 points moving smoothly (meaning without teleporting) along a line starting at A and B and then moving to each others starting locations have to pass each other.

A very obvious statement, but you can build on it to make the following statements as well.

---

A convex shape is a shape where any two points on the shape must be able to be joined with a straight line that stays inside the shape. Convex shapes include rectangles and star shapes and the shape of a comma. The shape of the letter 'c' is not convex, because it's got an alcove.
Dec 4, 2018 12:17
@Secret yes, for example the normal distribution
Dec 4, 2018 12:16
whats this family of rules called? I want to apply it to things that are not reals
