There are pairs of prime numbers which have certain properties: twin primes are two prime numbers exactly 2 apart, cousin primes are 4 apart and sexy primes (the name comes from Latin for "six") are 6 apart. This piece draws arcs showing the distances between consecutive pairs of twin, cousin and sexy primes. Prime numbers are plotted vertically as white circles, from top to bottom.
