Prime numbers
... essentially very uneven. That’s what makes it hard to attack problems like the following. Definition 3. Two prime numbers are called twin primes if their difference is 2. For example, 3 and 5 are a pair of twin primes. So are 41 and 43, and 101 and 103, and 809 and 811. The twin primes conjecture4 s ...
