Not sure I understand the significance of a last digit of 9 for a prime implying the next prime is likelier to end with a 1 and not a 9. After all, base 10 is arbitrary. Can someone explain whether similar such "conspiracies" occur for all bases?
- Tyr42 7y agoYeah, the article says they investigated in base 3 first. In that base, it can by 0, 1, or 2 mod 3 (for the final digit). Primes clearly aren't 0 mod 3, so all (not 3) primes end in 1 or 2. They found that primes "liked" to alternate between them.
