In mathematics

Fifty-nine is the 17th prime number. The next is sixty-one, with which it comprises a twin prime. 59 is an irregular prime,[1] a safe prime[2] and the 14th supersingular prime.[3] It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1. Since 15! + 1 is divisible by 59 but 59 is not one more than a multiple of 15, 59 is a Pillai prime.[4]

It is also a highly cototient number.[5]

There are 59 stellations of the icosahedron.[6]

59 is one of the factors that divides the smallest composite Euclid number. In this case 59 divides the Euclid number 13# + 1 = 2 × 3 × 5 × 7 × 11 × 13 + 1 = 59 × 509 = 30031.
