Assuming the black striped continue forever for "prime mod 1260", does this mean we can quickly weed out non prime numbers?

- christophilus 12y agoI was wondering that, myself. The magic number seems to be 210. (1260 is 210 * 6)
- christophilus 12y agoYou'll also notice that between the black stripes, there is a somewhat denser white stripe. A while back, I calculated the number of primes in those white stripes, and the number was a good bit higher than the over all average.
- pbhjpbhj 12y agoThis just seems to be a variation of the Sieve of Eratosthenes?
- christophilus 12y agoMaybe? Haven't heard of it.
