116 (one hundred [and] sixteen) is the natural number following 115 and preceding 117.

In mathematics

[edit]

116 is a noncototient, meaning that there is no solution to the equation mφ(m) = n, where φ stands for Euler's totient function.[1]

116! 1 is a factorial prime.[2]

There are 116 ternary Lyndon words of length six, and 116 irreducible polynomials of degree six over a three-element field, which form the basis of a free Lie algebra of dimension 116.[3]

There are 116 different ways of partitioning the numbers from 1 through 5 into subsets in such a way that, for every k, the union of the first k subsets is a consecutive sequence of integers.[4]

There are 116 different 6×6 Costas arrays.[5]

In science

[edit]

116 is the atomic number of livermorium.

In other fields

[edit]

Jiroemon Kimura, the oldest man to ever live, died with the age of 116.[6]
