WebIn fact, from now on a prime must be next to a multiple of 6. (Being next to a multiple of 3 is not enough. Look at 9, it has even numbers on each side, but 12 is next to odd numbers, then 15 is next to even numbers, etc.) (beyond 3) primes are next to a multiple of 6. Notice the "twin primes" 5 and 7 next to 6; then the twin primes 11 and 13 ...

WebThis superimposition reveals some interesting circularities: When you sum the 9 angles that hit the twin prime distribution channels dead center you get 1800. 1800/360=5; 1800/9=200. In turn, sum the 6 angles that hit equidistant between the twin prime distribution channels and you get 1080. 1080/360=3. 1080/6=180.
