| Jun 8, 2016 at 14:44 | comment | added | Bugs Bunny | Sorry, I misunderstood the notation $\{1,2,\ldots n_i\}$. I thought it referred to the order in the infinite set. I guess I must give an answer then. | |
| Jun 8, 2016 at 1:39 | comment | added | Farewell | Correction: It seems that he interpreted it as: "Is there an infinite subset of $\mathbb N$ such that there is some permutation of that set which gives that sum of every two adjacent elements is a prime number?" | |
| Jun 8, 2016 at 1:31 | comment | added | Farewell | @TonyHuynh Right. It seems that Bugs interpreted my question as: "Is there an infinite subset of $\mathbb N$ such that every two adjacent elements sum to a prime number?". I thought that my question was concise enough. | |
| Jun 8, 2016 at 0:06 | comment | added | Tony Huynh | @BugsBunny All numbers from $1$ to $n$ must appear exactly once. So, the question is, are there infinitely many $n$ such that the numbers from $1$ to $n$ can be permuted so that adjacent numbers sum to a prime number. | |
| Jun 7, 2016 at 14:06 | comment | added | Bugs Bunny | Why cannot you keep adding numbers so that the last sum is always prime? E.g.: 1,4,3,2,5,6,7,10,9,22,15... All you need is infinitely many primes | |
