- When I was in high school, I was playing around with twin primes and
- noticed that for the first few examples, the following was the case:
-
- Let the lower member of the r-th pair of twin primes by the n-th prime.
- Then if n is prime, it is the r-th prime. For example,
-
- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
- 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103
- 1 2 3 4 5 6 7 8 9
-
- When I was an undergraduate, I showed this to some friends of mine who
- checked it further on a computer and found that it breaks down fairly
- quickly beyond that point. However, it is still reasonable to ask whether
- it is approximately true. For example, does it seem to be consistent with
- anything that is known about the bounds for the number of twin primes less
- than x?
-
- Any comments are welcome.
