In other news, I've listed to the track "Steamed Hams intro but it's 8-bit" 1180 times.
It lasts for 13 seconds, meaning I've spent 4 hours 15 minutes and 40 seconds listening to it
Not all in one go obviously
but still, who's proud of me?
I know I am!

A matrix is antisymmetric, or skew-symmetric, if its transpose equals its negative. The transpose of a matrix can be obtained by reflecting its elements across the main diagonal. Examples of transpositions can be seen here: \\$\begin{pmatrix}11&12&13\\21&22&23\end{pmatrix}\rightarrow\begin{pmatrix}11

Write a program to print the first 26,355,867 prime numbers, from 2 to 499,999,993 inclusively. Or in other words, print all the prime numbers smaller the 500,000,000. The fastest code wins! The program must not use any preprocessed input. The results will be tested on my machine

Asking for last feedback on this (changed the task to not require outputting initial terms) cc @mypronounismonicareinstate @user202729 @xnor

6:25 AM
@Bubbler I suspect that there might be some way to cheat if initial terms are not required.
@AviFS The "3 days" rule is only specified in a post in the sandbox FAQ. If most people agree that it's important enough to be in the main sandbox "question" post then it can be moved there (someone may want to make a meta post about that)
Although (I suspect that) some users active on main already-never visit the sandbox (or review the sandbox posts not as carefully), so longer might not be better.

@user202729 How? It is my intention to give some room for finding the recurrence without the terms.

@bubbler ... thinking about it again, it's not that easy. But it's still possible to output the product of every candidate polynomial.
For example... if I somehow can prove that the length is <= 2m , all coefficients are integers, and abs(coefficients) is <= 2^m then the program can output the product of every such polynomial.

6:45 AM
@user202729 Then I could limit the order k to 2^m or something

Or polynomial in m.

I don't think polynomial will work, because empirically the minimal order for small m looks like O(2^(m/2)).

But the matrix size is polynomial in m.
And the minimal polynomial degree has the size <= matrix size?

To me it's 2^m rows/columns, and I don't see any trivial way to shrink it other than vertical mirror images

... right.
Then exponential in m.
2^m is better, I guess.

7:10 AM
Good, now it's limited to k<=2^m.

This meta question by @xnor addresses allowed outputs for [tag:decision problems]. But in that question the goal isn't to make a policy, but to help with a decision I often have to make when writing challenges
I think we do need a policy, so that when people don't specify we can assume some default output allowed in [tag:decision problems]. Should we post a new meta question and answers so people can vote? Or do we use @xnor's question and its answers to decide the policy?

@HighlyRadioactive Refresh the page the next day.
(Did you only upvote question today?)

Wdym?

@HighlyRadioactive You need to upvote questions only, in order to get the maximum 40 votes.

Why is there this restriction
No I upvoted almost questions only

@Third-party'Chef' What you forgot your own language?

@HighlyRadioactive I created so many languages on esolangs.org such that I forgot almost all of them...

You should've make a list.
I like to surf on the internet language lists
That's how I found 1+

@LuisMendo Third option: Post answers to the existing Default I/O post and let people vote.

@Bubbler Yas, sctually that's what I meant with my second option: use its answers, including new ones

But that would require @xnor's transforming the original question into a policy question
