Sexy primesSexy primes are two prime numbers, wherein their difference is 6. I got this from a video on YouTube : http://www.youtube.com/watch?v=WJ12DYBuazY 246 pages on Prime Numbers Wiki (+1) #2 20130427 21:47:15

Re: Sexy primesIs 6 the smallest possible common difference in AP of more than three primes? 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #8 20130429 06:18:11
Re: Sexy primesThere are many with a common difference of 6, but none smaller. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #9 20130429 22:59:10
Re: Sexy primesWell, first note that the common difference must be an even number, and if it is less than 6, then it must be either 2 or 4. Also notice that if two numbers differ by 2, 4 or 8, they have different remainders modulo 3. This means that in three numbers in an AP with common difference 2 or 4, one will surely be divisible by 3. It is now easily proved that an AP of 4 or more terms and common difference 2 or 4 cannot exist. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #10 20130430 10:46:09
Re: Sexy primesThanks for the proof 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.'

Re: Sexy primesThere is one that I came up with that is quite simple. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #12 20130430 10:51:59
Re: Sexy primesAnd that is?

Re: Sexy primesBoxes and dashes like in combinatorics! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #14 20130430 11:01:07
Re: Sexy primesPlease go ahead 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #15 20130430 11:11:39
Re: Sexy primesWe can view the number line in terms of boxes and dashes. The boxes are multiples of three, the dashes are the two numbers between each multiple of 3 that is greater than 3. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: Sexy primesThat is the same as my proof.

Re: Sexy primesBut it does not require any mathematical jargon or concepts other than counting. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #18 20130430 11:20:50
Re: Sexy primesIt is the same proof worded differently. The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment #19 20130430 11:23:50
