Even if I’m misunderstanding how this is supposed to work for odd n, this claim fails for plenty of even n. n = 14: fails on row 13, col 3 n = 20: fails on row 17, col 8 n = 30: fails on row 17, col 7 n = 38: fails on row 37, col 8 n = 44: fails on row 31, col 2 n = 50: fails on row 43, col 13 …
Those are some pretty basic checks to miss. Perhaps I've misread OP's claim.

#92Is there are particular reasoning or meaning to each dot being 6 numbers? Is there any significant changes if you pick other numbers per dot, following the same pattern? Based on the linked explanation here: https://beta.observablehq.com/@montyxcantsin/unwinding-the-u...

The claim is that using N numbers per square will result in the pattern holding for N rows, for arbitrarily large N.

He's not claiming it holds for _all_ n, just for _many_ n.
Re: An Interesting Pattern in the Prime Numbers: Parallax Compression
#95I am a little confused. When it says that each square corresponds to n sequential numbers, does it mean that the first square is the first n, and the second square (which is on the second row) is the first n after those, and the third square (also in the second row) has the first n after those, and so on, Or, do the regions overlap? I tried to look at the first 4 rows for n=5, but did not see the pattern depicted (ea…
For fixed n, a block (x,y) contains the numbers n/2 y^2-n/2 y + yz + x for all 0 <= z < n.

Is that
((n/2) * y^2) - ((n/2) * y) + (y * z) + x ? (For z ranging from 0 to n)
If so, alright, that makes more sense to me, thanks.
So, n * (y * (y-1)/2) + x + y * z ?
Edit: does HN have an escape character to deal with the asterisks?

Their picture is correct, but only because they are doing something more ridiculous than this. Every one of the squares in their picture represents 75 numbers, not 5 numbers.
Click on the definition of T, and you see exactly the A054521 formula. T = (n, k) => { return (GCD(n, k) == 1) ? 1 : 0; } The given code doesn’t use primes, primesSet, or isPrime at all.

#98Looking at the layman letters that my institute gets on a regular basis, I can say, that this is unfortunately a recurring theme with amateur mathematicians: They fail to state their basic definitions and assumptions and seem all to eager to dive right into applications, be it computer graphics, cryptography or finance.
More to the point: This picture seems from a cursory inspection to plot T(k,n) with n=row, k=column from the top left. But why is this interesting?
Re: An Interesting Pattern in the Prime Numbers: Parallax Compression
#99The pattern looks nice, but I would have asked some mathematicians before announcing this as something novel.
I understand what you mean, but how many great breakthroughs in history were where someone shared the foundation of an idea and then another formalized it?
In the more mathematical realm in information theory, turbo codes came out of nowhere by people who were not experts in the field of FEC. Their efficiency far surpassed other methods of the time, to the point that their results in the conference paper were doubted. They didn't have any understanding at the time of why they worked well, they just published results.
Lots of physical phenomena start as simple observations that are later worked into theoretical frameworks. The photoelectric effect comes to mind.
