## Statistical Bias in the Distribution of Prime Pairs and Isolated Primes

**Authors:** Waldemar Puszkarz

Computer experiments reveal that twin primes tend to center on squareful multiples of 6 more often than on squarefree multiples of 6 compared to what should be expected from the ratio of the number of squareful multiples of 6 to the number of squarefree multiples of 6 equal $\pi^2/3-1$, or ca 2.290. For multiples of 6 surrounded by twin primes, this ratio is 2.427 (for the first $10^{10}$ primes), a relative difference of ca $6.0\%$ measured against the expected value. A deviation from the expected value of this ratio, ca $1.9\%$, exists also for isolated primes. These numbers show that primes are drawn excessively to squareful numbers, a phenomenon most likely previously unknown.
