Primes have always fascinated me because they feel like the building blocks of numbers. It's remarkable to think that every other natural number greater than 1 can be decomposed into a unique product of primes. It's almost as if primes are the elemental components of the number system, much like atoms are the fundamental building blocks of matter. This fundamental property of primes is what makes them so intriguing and important for us humans. At least that is what I think.

… I didn’t even realise but apparently I’ve seen all the videos, it was just long enough between them for me to not notice

It must've been very cool to find out that the prime properties of this seemingly arbitrary sequence is related to a very active area of research, namely primes in arithmetic progressions. In particular, I find it really neat that these sorts of questions are playful enough that you could imagine Fermat or Euler studying them, but we can now describe them with our more modern techniques.

I don't think anyone's posted the reason as to why 3 is the second number in every cluster, so for those curious, it's stems from the fact that every index with nontrivial gcd is either 0 or 2 mod 3. This comes from simple induction: the first index indeed satisfies the condition, and if the previous index n was 0 mod 3 then 2n-1 isn't divisible by 3, so the smallest prime p dividing it is -1 or 1 mod 6, leading to the new index being (p-1)/2=0 or 2 mod 3 more than the previous one; likewise, if the previous index n was 2 mod 3, then 2n-1 is divisible by 3, so the next index shifts by (3-1)/2=1, making it 0 mod 3. Because of that, when we get to an index t that makes 2t-1 prime, 2t-1 is also the index of that prime (since the index goes from t to t+(2t-1-1)/2=2t-1), and since the index is prime and more than 3, it isn't 0 mod 3, so it's 2 mod 3, leading to the next number 2(2t-1)-1 in the sequence being 2*2-1=0 mod 3 i.e. the number after the prime must be 3.

I am interested in the generalized REPUNT primes. In base two, these would be the Mersienrs

Observed pattern. In the first cluster, 5 is followed by 3. In the next 11 is followed by 3. In the fourth, starting with 47, 5 is again followed by 3. In the fifth, starting with 101, 7 is not followed by 3, but 11 is. 13 is not. Scanning down, it appears that whenever 5 or 11 appear in a cluster they are followed by 3. But this does not appear to hold for 7 and 13 -- which also appear to never occur as the first terms of any cluster. So perhaps for numbers that start clusters, if they reappear in other clusters, they do so followed by 3. And numbers that do not start clusters, if they reappear in other clusters, they do so not followed by 3.

Great job! At first I thought that this was too hard for me, but eventually I understood almost everything. So cool.

What a wonderful video. I wish every math paper could be explained in such a wonderful video format like this.

21:50 That sequence is interesting. If you take the first 2 to be in the 2nd position (so the sequence just has no first position) then all the primes, other than 3, seem to appear in their own numbered position (i.e. 2 in the 2nd pos, 5 in the 5th, 7 in the 7th). You then have other primes appearing, and at intervals corresponding to prime multiples of that prime (e.g. 5 in the 5th, (2x5)th, (3x5)th and (5x5)th positions) though it looks like possibly any given prime will only appear in the sequence a 'few' times (for some definition of few) then never again.

in the first 10000 terms, there are 5 instances of 5, the last one on n=25=5*5 one instance of 7. 3 instances of 11, last one on 33=11*3. 8 instances of 13 (7th on 91=7*13, 8th on 169=13*13). 17 appears three times, last on 51=17*3. 19 appears once. For the following the appearances along the sequence continue to be equally spaced: 23 appears five times. 29 five times. 31 once. 37 once. 41 three times. 43 five times. 47 five times. 53 three times. 59 five times. 61 seven times. 67 five times. 71 three times. 73 thirteen times, last one on n=949=73*13. 79 once. 83 three times. 89 appears 15 times, last on 1335=89*15. There is a nice pattern but it is a little disturbing how 13 appears at n=169.

I feel like this is related to Dirichlet progressions. I'm actually doing applied research into finding the upper bound of the first p of the form sn+1, which is MUCH easier to prove the primality of using a deterministic Miller-Rabin test. So far, it looks like p(s) 1, you can find an N such that the bound holds for s>N. I thought it was related, especially due to the clustering in a log-log plot, you get that same kind of behaviour when graphing the strictly increasing subset of s, p(s) (just like ignoring the 1s).

it's quite easy to prove that when n is prime P(n) =n for all odd primes >3 because C[n] is the product of numbers strictly smaller than n. It gets more interesting in the case of P(n*n) where n is prime. this requires that there exists some prime q which divides a*n -1 for some a in {2,3,...,n-1}. For example P(5*5) is saved because 19 divides 5*4 -1 which means that: If we make the hypothesis that for all odd primes p>3 there exists another prime q such that q = a*p - 1 for some a in {2,3,...,n-1} then this hypothesis is implied to be true if Cloitre's variant makes only primes. equally if this hypothesis if false, that implies Cloitre's variant doesn't only primes. (which is not an if and only if because if the hypothesis is true it doesn't imply Cloitre's variant makes only primes.)

Dude! Been working on this very problem for like a decade, mad respect for the explanatory work! ✊

this was really fun and educative to watch

I saw 3 repeating on every 2 numbers [EDIT: In some parts], 7 and 11 were appearing too often but I didn't see exactly where. Also great video!

Ey dude, at around 10:15 in the video, if you take the sum + the prime you wanted - 1 you get the next sum in the sequence. If you do that again with the new sum you get the next sum. But you surely already have seen that showed why, and I missed it. Great video man.

What I saw first at 3:00 is that the 3’s are on opposite sides of other primes, like the twin prime conjecture

The forward-moving algorithm works for any input number: Given a number n Calculate the target p=(2*n - 1) Find the smallest prime factor of p=>pf Update n += (pf-1)/2 For example, start with n=44: 44 p=87 pf=3 p=89 pf=89 89 p=177 pf=3 p=179 pf=179 179 p=357 pf=3 p=359 pf=359 359 p=717 pf=3 p=719 pf=719 719 p=1437 pf=3 p=1439 pf=1439 1439 p=2877 pf=3 p=2879 pf=2879 2879 p=5757 pf=3 p=5759 pf=13 p=5771 pf=29 p=5799 pf=3 p=5801 pf=5801 5801 (etc) All of these generate factors and/or prime numbers (obviously... when you think about it).

What is said from 8:04 prevents from looping over all values of a cluster and sets its boundaries. It also means that the last value's index of the cluster is enough to describe it and averaging the values or the indexes could be unnecessary. It also says that there might be something hidden in the gap between two clusters. This saved me weeks, maybe months of work and much CPU time. Deserves the Fields to me. Thank you Professor 😁

Great visualization

At 2:51, I noticed a more general version of the doubling pattern which seems to hold true everywhere (but I haven't proven it). If you let x and y be two "largest so far" primes in the sequence, then y = 2 * x + p_s - p_n - 1, where p_s is the sum of the primes in the sequence between x and y, and p_t is the number of primes between x and y. (Trivially, you can put the ones back in the sequence and use the same formula, since the ones are just canceled out between p_s and p_n). For example: ... 467, 3, 5, 3, 941 ... x = 467 y = 941 p_s = 3 + 5 + 3 = 11 p_n = 3 2*x + p_s - p_n -1 = 934 + 11 - 3 - 1 = 941 The 2*x + 1 case is just a special case of this: ... 5, 3, 11... p_s = 3 p_n = 1 2*x + p_s - p_n - 1 = 2*x + 3 - 1 - 1 = 2*x + 1 And you don't even have to do this with two consecutive "largest so far" primes. For example: ... 47, 3, 5, 3, 101, 3, 7, 11, 3, 13, 233, 3, 467 ... x = 47 y = 467 p_s = 3 + 5 + 3 + 101 + 3 + 7 + 11 + 3 + 13 + 233 + 3 = 385 p_t = 11 2*x + p_s - p_n - 1 = 94 + 385 - 11 - 1 = 467 I'm not sure how this relates to everything else, or if it's useful (it doesn't actually predict the jumps), but it's interesting.

@rasowa2958

This is because every prime bumps R(n) up to 3*n. See it at 1:52. So: R(x) = 3*x R(y) = 3*y = R(x) + p_s + (y - x - p_n - 1) + y this is because R(y) is a result of adding: - R(x) - primes between x and y (p_s) - ones between x and y in amount: y - x - p_n - 1 - prime y Now solve it for y: 3*y = 3*x + p_s + y - x - p_n - 1 + y and the result is your formula: y = 2*x + p_s - p_n - 1

Perhaps an interesting observation is that the first prime you still havent produced with your sequence if fairly close to the first non-prime at 19:43

I tried to follow your video. Very impressed by your efforts in this direction (of trying to generate primes). However, may be there are better and more elegant ways to generate primes. For me, Primes are linked to Quantum Computing. Just as Boole came up with Boolean Algebra which was the foundation for the Binary Digital World, we have to envision how Quantum Computing logic will help us to instantaneously decipher (or decompose) some of the largest numbers which we can envision into it's Prime Components. I am still trying to wrap my head around how this new computing paradigm will do that, but that is the way to go, in my opinion.

SUPER! This is really great work!

Thanks a lot!

Since you ask, at 2:45 the most obvious pattern was the lack of 2s, followed by the sequence 3 5 3 being common. At 4:17 I was surprised you didn't mention the striking pattern that many primes first occur where n is equal to that prime. In fact, this is so prevalent that at 7:40 you highlighted the primes themselves when you were actually talking about their indices.

awesome video, super interesting.Thanks!

7:33 Would it make more sense to do a geometric mean of each cluster than an arithmetic mean?

Impressive work. To make your own theorem and yet explain it so simply is amazing. Kudos
