[@jAujAl1]

I remember being obsessed with Conway's game of life and trying to make a 1D version of it on a spreadsheet (with time progressing on the vertical axis). In doing so I accidentally discovered rule 126 (if three adjacent cells have a sum of 1 or 2, then the center cell underneath has a value of 1, otherwise it has a value of 0) and created a Sierpinski triangle, which pleased me greatly. I assume it's a specific case of your class of fractals, and follows the same rule as your n=3 instance at 4:17. For those wanting to replicate it, in LibreOffice Calc, you can paste the formula =IF(OR(SUM(A1:C1)=1,SUM(A1:C1)=2),1,0) in the B2 cell and drag the formula across the whole sheet (don't drag it on the col A and row 1 though, leave those empty), and write 1 in any cell in the first row. It's particularly fun to see the patterns it builds when you have more than one full cell in your initial conditions.

[@angelsachse9610]

Very smart idea! I had a similar obsession a few years ago.

[@40watt53]

now i gotta see conways game of life with time on the third axis

[@nomekop777]

There's another Sierpinski triangle in Conway's game of life. If you make a line with length 2^n, and step for long enough (I think 2^n-1 steps but I don't remember) it makes two Sierpinski triangles touching on the bottom so it makes a rhombus. I have no idea why, but it's fascinating

[@logicroar]

rule 150 generates the modulo 2 fractal

[@logicroar]

im pretty sure at least.

[@digitsstuff6521]

That's pretty interesting, this is like a fractal that you can infinitely zoom out on instead of infinitely zooming in on. One thing I've noticed is that the level 2 one is actually just rule 150, the 1D cellular automata, which is "one of the eight additive elementary cellular automata" according to Wolfram and as a result, it's already fairly well studied. Looking at Rule 150 might give more insight to the family itself.

[@dylanherrera5395]

not really, thats kinda the same as saying, oh if i copy this triangle down there, and down there, i can zoom out, so the Sierpinski triangle is actually infinitely large and you can zoom out, not in

[@PeterNerlich]

This was super interesting! I wonder if that has already investigated before. If not, I'm definitely rooting for the term Kuvina Triangle! You obviously put a lot of work in these videos, and the content is really good. I'm kind of amazed that you put this video out so quickly after the last one *checks channel* 13 days ago. This is severely awesome ^^ All the best to you! Hope you have fun, and don't overwork yourself.

[@Kuvina]

thank you! It's really considerate of you to be concerned whether I'm overworking myself, and I assure you I'm not. I do these for fun, and I have a lot more time for that now that it's summer break and I finished my 3rd year of college.

[@Tarou9000]

​​@@Kuvina don't know if you've figured this out but i found a connection between these fractals and John Conway's game of life. As you may know John Conway's game of life or "Life" for short is a case of celular automaton a.k.a. a game of zero players, wich means once the initial state is set; the "game" plays itself. The thing is that the Sierpinski Triangle can also be generated with the simple rules that make celular automaton so special, the difference is that while life takes place in a 2 dimensional grid, the Sierpinski Triangle (or any of your versions) in a 1 dimensional array, but each generation is plotted in each row of the triangles, unlike with like, in wich you usually just see one iteration at a time, here's what I mean: To start the Sierpinski Triangle start with an infinite array of black squares with only one being white: ⬜⬛⬛⬛⬛⬛⬛⬛ This is the first iteration/row of the Sierpinski triangle, for the next iteration each square checks if the square above and the one above to the left have different states, giving arise to the next generation: ⬜⬜⬛⬛⬛⬛⬛⬛ This operation of checking if two states are different is also known as the bitwise xor operation, a.k.a. the summation mod 2, wich also gives arise to the pascal triangle. Iterating this process over and over again, such as done in celular automaton finally generates the Sierpinski Triangle: ⬜⬛⬛⬛⬛⬛⬛⬛ ⬜⬜⬛⬛⬛⬛⬛⬛ ⬜⬛⬜⬛⬛⬛⬛⬛ ⬜⬜⬜⬜⬛⬛⬛⬛ ⬜⬛⬛⬛⬜⬛⬛⬛ ⬜⬜⬛⬛⬜⬜⬛⬛ ⬜⬛⬜⬛⬜⬛⬜⬛ ⬜⬜⬜⬜⬜⬜⬜⬜ Each of your own versions can also be expressed as a celular automaton with its unique rules, with the modulus being the ammount of different states/colors.

[@rojnx9]

@@Tarou9000 For anyone else reading these one dimensional cellular automata are called the Elementary Cellular Automata (ECA), and there is a lot of research done into these. The most famous one is called rule 22 (from the binary number that defines its ruleset) which creates the Sierpinski triangle.

Heya, I came up with this 2 years ago! Cool that someone else thought of it independently, though I took it a bit farther in a different direction. This isn't really a 2d fractal, or well it is, but it can be thought of as having 1 spacial dimension and 1 temporal. I use 2 spacial and a time dimension. There is a defined list of "neighbors", and between each update each cell will add itself to all its neighbors. Some especially pretty ones are the neighbors being knights moves, and having it reach in all 8 directions!

I saw you in 3blue1brown's comment section, not gonna lie I dont regret coming here.

[@Gizmote]

The basis for this fractal is the trinomial triangle, so named because the terms of each row correspond to the coefficients of expansions of trinomial expressions. I independently discovered this when trying to figure out how to describe the outputs of the probability distribution of rolling 3 dice, then found there's already a body of research on it, from Euler to Wikipedia! I love your variations of it, and I particularly like how the fractal for n = 127 looks like it has cool sunglasses on, and how product 48 makes the pan flag. You might also be interested in Rule 90 and other related 1D cellular cellular automata. I spent a while nerding out about these.

I think bi versions are most uninteresting. It's just "Prime numbers dividing triannge into T(n) pieces and composite numbers reflecting their prime factors". Bi skew versions are same, but skewed. I think shadow skew versions are most interesting, because they're not actually skewed and primes make unique pattern that are different from regular versions. Product version are also interesting, because they don't make triangles, just stripes with patterns.

The Kuvina triangle fractal looks very similar to the IFS version of the Sierpinski triangle but with an additional choice point at the center of the base of the triangle, which is also a projection of the 3D Sierpinski pyramid. The generated family appears to be an extension of the way that 1D cellular automata have been shared for quite some time.

[@josephmellor7641]

I've done a lot of work on the p = 5 version with rows with a finite width where it wraps around, so if you have a row with m elements, the rule for x[n + 1] is x[n + 1][k] = (x_n[(k - 1 + m) % m] + x_n[k] + x_n[(k + 1) % m]) % p In my case, I wanted to study questions like "How long does it go before it repeats?" and "How long is the delay before it gets into a cycle?" It turns out you can study both of those by converting the rule to a matrix and then finding the generalized eigenvalues in some finite field of characteristic p. The problem with this approach is that it only works if p is prime, but this video gave me an idea. As you've pointed out, though, you can make the composite triangles out of the triangles made of their prime factors. I can then use this insight to study the p = 6 case by studying the p = 2 and the p = 3 case and then combining their results with the Chinese Remainder Theorem. This should definitely work as long as p can be factored into unique primes, but it might get stuck on cases like p = 4. I'll have to think more about it. Anyway, I'm definitely subscribing to this channel. Keep making cool stuff.

The formula for the product version looks similar to things which are often used as pseudorandom number generators, and the patterns exhibit some of the behaviours found there. For some moduli it falls into a repeating pattern, for others it goes through all possible state values in a randomish way. Except here there are infinitely many states, so some of the patterns will continue to grow forever without repeating.

In higher maths land it's considered a bit self-aggrandizing to name anything at all after yourself. You give it a generic name and then it's up to other investigators to decide what to call it in their own work. Sometimes people will put some effort into figuring out who really came up with an idea first, and call it by that person's name; or they will choose the person who did the most to popularize or investigate the object. Ideally of course, things get defined mathematically, so it doesn't matter which option is taken.
