@msh210 @Stiv new answers by fishy new user seem to be AI generated. Please investigate.

what if it's a ref to the classic rickroll?
Aug 20, 2023 22:30
Dam... that's somewhat of an overreaction?
Aug 20, 2023 15:25
@Jafe is Roughing it a reference to good ol' Twain?
Aug 20, 2023 14:45
Judging from the username and the ban on Philosophy, 'The Coin Conundrum' 's author seems a little suspicious.
Aug 11, 2023 02:30
Also, I'm confused about the whole 'use only puzzling as a source' thing. Back when we had xkcd 1xxx, there were many posts that used the comic itself - i.e. a website that can go down and is not under control of Puxxling

leads to something about rays

I found 2 in one go...
Aug 15, 2023 22:02
Agree. If you relax the restrictions, there are multiple solutions.
Aug 15, 2023 21:41
@fljx Odd, because when I counted I got one loop. Should I share my attempt?
Aug 15, 2023 21:36
My solution appears to still separate the torus into two sections. Is this fine?
Aug 15, 2023 21:36
So... How do you solution check?
Aug 15, 2023 21:36
Executive pleading for everyone to pause on this problem for a while, because I am really close to an answer.
Aug 15, 2023 21:36
I'm confused about the torus requirement. Do the top and bottom edges have to have the same configuration?
Aug 15, 2023 21:36

'Among number digit 3 nothing groups' is my first attempt at finding the hint. I think this means there's something about numbers next to each other...
Aug 9, 2023 21:52
I think the 'hills' are actuall a car, it makes sense imo
Aug 9, 2023 21:49
I guess the same prob
Aug 9, 2023 21:48
so the other safe prime must be a 5! "Two digits are already given" well in a very encrypted way? Are the two digits the safe primes I was talking about or were they different
Aug 9, 2023 21:39
also is the lowercase x a typo or intentional?
Aug 9, 2023 21:39
the only thing I have managed to find is three red herrings. mmm, yummy!
Aug 9, 2023 21:37
oops, 7 is the safe prime, 3 is the germain prime
Aug 9, 2023 21:36
@Lezzup does the word search contain anything fundamental to the solution of the puzzle?
Aug 9, 2023 21:36
3 is the only mersenne for that
Aug 9, 2023 21:35
we need to find a mersenne number that's also a safe prime?
Aug 9, 2023 21:35
Mersenne Blue could be a reference to mersenne numbers
Aug 9, 2023 21:34
alright here's my rambling stream of conciousness
 
Jul 27, 2023 21:51
Ah, I understand. Just for giggles, how long would testing all of that on a computer take? 100 years?
Jul 27, 2023 21:46
Hang on, I'm quite lost. If we assume Step 1, would Step 2 neccessarily be correct?
Jul 27, 2023 21:36
Yes, I have read that. My main worry with the chromatic number approach is that the number of bits sent is the log2 of the chromatic number, meaning that it becomes more and more hard to find a lower bound as the lower bounds increase.
Jul 27, 2023 21:31
-Because then Step 1 would fail, and there would be a bad-case scenario for step 2 as pointed out by the OP of the answer: "I'm looking at the worst-case scenario, which is 45 1s out of 90."
Jul 27, 2023 21:19
@DrXorile I think also that you could split Step 1 into an 89 bit array and then send the number of the last bit. That way, it guarantees there can't be the same amount of 0s and 1s.
Jul 27, 2023 21:16
Doesn't any hash function of less than 90 bits as output guarantee a collision by the pigeonhole principle? Or can we use the added info of 15 0's and 15 1's flipped to our advantage?
Jul 27, 2023 18:26
@DrXorile Oops, I didn't catch on to the fact that we abandoned the CRC method
Jul 27, 2023 18:23
since the main problem is when there are 15 zeros and 15 ones flipped, we could use a method similar to the top answer's method. Of course parity fails, but some sort of extension of parity could work.
Jul 27, 2023 18:15
I think i've been trying to improve Lezzup's method so that it actualy works
Jul 27, 2023 17:50
Can we attempt to use a larger polynomial?
 
Jan 12, 2021 16:36
Like, a making sense representation?
Jan 12, 2021 16:31
Now you can!
Jan 12, 2021 16:30
@RFS You can't talk in chat...
Jan 12, 2021 16:30
Can't you compute this as an iterated integral?
Jan 12, 2021 16:30
What about WolframAlpha?
Jan 12, 2021 16:30
Also, did you make a mistake, because you mean $h < w$?
Jan 12, 2021 16:30
Why are you integrating to $\sqrt{w^2-h^2}$?
Jan 12, 2021 16:30
have you tried WolframAlpha?
Jan 12, 2021 16:30
Do you not know what a double integral is?
Jan 12, 2021 16:30
@GNUSupporter8964民主女神地下教會 I think you mean $\sqrt{H^2 - w^2}$.
Jan 12, 2021 16:30
What's a "blackbox"?
 
Jan 9, 2021 18:43
Displacement is 0, distance is 2pi?
