### Twin prime

There is a cyclic structure in the **twin primes** and you can see that in the prime number cross.

##### Explanation

The causes are:

• | The number –1 is a reflection relative to the number +1. With the imaginary unit you can express it as |

• | The number 0 can be divided by all other numbers and is therefore not prime. |

• | The number 1 can also be written as |

• | The number 2 is a prime number. Because of this other even numbers can not be primes. |

• | The number 3 is a prime number. Because of this all multiples of three can not be primes. |

• | From the number 5 all primes have the form 6 |

• | After the number 24 the regularity breaks, because the number 25 comes from previous primes, because 25 = 5 × 5. You can see this happen again and again later, like with 35 = 5 × 7 and with 49 = 7 × 7 and so on. |
