A PRIME CONSPIRACYYou might assume that prime numbers are distributed randomly -- a reasonable assumption.However, we now have empirical evidence that it’s not true. SUMMARY
PRIMES ENDING IN 9 ARE MORE OFTEN FOLLOWED BY PRIMES ENDING IN 1
PRIMES ENDING IN 1 ARE MORE OFTEN FOLLOWED BY PRIMES ENDING IN 2
PRIMES ENDING IN 2 ARE MORE OFTEN FOLLOWED BY PRIMES ENDING IN 1
PRIMES ENDING IN 3 ARE MORE OFTEN FOLLOWED BY PRIMES ENDING IN 9 [than in 1 or 7]
If your prime ends in 3, it’s more likely that the next prime will end in 9 than in 1 or 7.
In summary, mathematical researchers found that 1 is followed by:
* 1 about 18% of the time
* 3 about 30% of the time
* 7 about 30% of the time
* 9 about 22% of the time
They found similar results when they started with primes that ended in 3, 7 or 9 variations, but with repeated last digits the least common.
The bias persists, but slowly decreases, as numbers get larger.Full details here:http://hackaday.com/2016/03/14/prime-numbers-are-stranger-than-you-thought/https://www.quantamagazine.org/20160313-mathematicians-discover-prime-conspiracy/
