## prime number patterns | |

TonyM User ID: 628955 Australia 04/30/2012 08:32 AM Report Abusive Post Report Copyright Violation | Love this thread and will return in more detail. I am prime tragic, spending more than a few thousand hours being obsessed by them. I do know there are patterns in the primes and think I have some unique discoveries to share with the world when I get enough time to formalise them - I am not a mathematician so this is very difficult. The method I use to analyse the primes however is a little different to most. The first thing I would say is the one pattern you all must recognise is the one that results from the definition of primes, that they are only divisible by one and themselves - perhaps you think I am telling you the obvious but most people overlook this and search for patterns that result from the primes, patterns which are doomed to end or have exceptions because primes are an infinitely small subset of the all integers which are an infinitely big set. And since the primes are infinite there will be many opportunities for patterns to occur that are artifacts and not a fact of the primes. Hint - Look at how patterns form not what patterns you see.My own theory proves a number of the postulates, most of which have already been proven by other means and some of which have not, but I need to demonstrate this more thoroughly. This is because my theory seems obviously extensible to infinity through all primes however I need to run very big numbers to prove it and make sure there is not something I overlooked. My theory is mature enough that I expect an exception to disprove it would occur fairly quickly and thus damage if not destroy my theory but I am hopeful - with good reason I think this will not be the case. I have not found a mathematician yet who would co-operate with me who would not be concerned I am a nut, and I have not found one I can trust. Mostly due to insufficient time trying to identify someone. TonyM |

What are you trying to achieve now, writing a computer program to test your theories? |

TonyM User ID: 628955 Australia 05/01/2012 04:01 AM Report Abusive Post Report Copyright Violation | I suppose the Trust is just not just for the ideas but that they will be respectful to a non professional. I am quite prepared to accept criticism but not dismissal. It is not even that, I am very busy with much in my life and whilst I am prepared to put in more time on this fanciful idea, that "I may have something new to add", I don't want to waste my time. A sentiment no doubt any collaborator will share. My Programming skills are strong but limited and it is too time consuming for someone with the less than ideal skills. Especially when I want to do non standard manipulations on big numbers that don't fit into standard binary numbers. I must say (sorry without references) some of the posts in this thread are "right on" with my view of the primes. Regards TonyM |

Anonymous Coward User ID: 1526134 United States 05/02/2012 01:34 PM Report Abusive Post Report Copyright Violation | First, big disclaimer, I'm not technically proficient in numbers any longer. it's been a long time for me to do math of any kind. But I noticed a post on here the other day that got me just to look at the problem for the first time for me. I know there are some serious math whizes on this site, so hope I can follow. Quoting: Honestly I don't know if some of the initial patterns in primes have already been talked about before, doing some research it's hard for me to understand the mathematical jargon. In my the simplest basic layman's terms, which is the only thing I can use in my case, when I look at the spacing between primes, lots of 3's, 5's, 7's, 9's, 11's and 13's. This has got to be a pattern of some kind! Now I've only looked at numbers up to 400, so I should probably do to at least 1,000. Maybe soon. But still another pattern that's coming up instantly is two prime numbers sandwiching a non-prime. Like 5 6 7. 5 and 7 of course being prime. And when you look at those double spaced primes, they occur with some regularity around the 10 count. like 239 240 241 for example. And when it sandwiches a perfect ten, the spacing til the next one seems to very regularly be a multiple of 30. And when the sandwich doesn't exactly land on the 10, it's always a step back (17 18 19) or one forward (41 42 43). When it's forward, their occurrences are also in multiples of 30 from the last, and when back, also in multiples of 30. Arrgh! Still the trick is trying to figure out the precise pattern, which I can't. And then the troublesome lone single primes, which don't have a real discernable pattern thus far. I can see now why no one's been able to predict thus far! I hope what I've said can be discerned and hopefully someone can tell me if I've given any thing new or not to the puzzle. Anonymous Coward 13669854 Here's a pattern for all prime numbers greater than 2. It's my hypothesis but I've not set about a proof. All prime numbers greater than 2 make an incomplete quadrangle. In other words, if you try to form a matrix to represent a prime number the matrix will always be "missing the corner" For example, three can be represented as XX X and four (not prime) XX XX The three represented above is missing a value in the lower right corner. Eight (not prime) can be formed with a matrix in a variety of ways For example XXXX XXXX or XX XX XX XX Which makes a complete matrix or "quadralangle" But seven , which is prime, can never make a complete matrix or "quadrangle" no matter how you try to form the matrix i.e. XXXX XXX or XX XX XX X Thus my conjecture is for all prime numbers, no matter how large, will never make a complete quadrangle. I don't know if there is prexisting or current work that already presented this perspective, or if this is just a trivial property of prime numbers, but I've never encountered it in any text book, and who know, this might be a very first. And just to think if it is it was made by an AC on GLP! hahahahaha |

TonyM User ID: 767192 Australia 05/02/2012 09:35 PM Report Abusive Post Report Copyright Violation | After two, no Prime is an even number. On the surface this would suggest no rectangle can be formed after 2 by primes. Quick Conjecture The Square, Cube of primes etc also form rectangles but are not prime. The need not be even as well eg; 9 Fact I have established. If progressively considering the primality from 1,2... the first possible prime (known to that point) to be excluded from primality is the Square of the current prime. Given every non prime must be the product of two (earlier) primes then the product will always be even and capable of being a rectangle as at least it can be two x any number. |

Quoting: If progressively considering the primality from 1,2... the first possible prime (known to that point) to be excluded from primality is the Square of the current prime. TonyM 767192 I'm working through an example of your description for clarity on my part: " progressively considering the primality from 1,2..."1, 2 (prime), 3 (prime), 4 , 5 (prime) 6, 7 (prime)I'm stopping here at 7, which we will call our " current prime".Then you say " the first possible prime (known to that point) to be excluded from primality is the Square of the current prime"Which would be 7x7=49, so we know 49 fails the primality test. I am slightly confused why you say it is the first, I could argue that the first to be excluded would be the lowest product of two primes a and b (a can also equal b) beyond our current prime, in this case 3x3=9. Unless you have a list of operations that you perform in order, to exclude values from primality.Given every non prime must be the product of two (earlier) primes then the product will always be even and capable of being a rectangle as at least it can be two x any number. Quoting: TonyM 767192 I'm confused here, 15 is non prime and is the product of 3 and 5, yet it is not even and is a rectangle. Hope you can clear up my confusion, thanks. |
