problem

Let

\mathbb{Z}/n\mathbb{Z}

denote the set of integers considered modulo

n

(hence

\mathbb{Z}/n\mathbb{Z}

has

n

elements). Find all positive integers

n

for which there exists a bijective function

g: \mathbb{Z}/n\mathbb{Z} \to \mathbb{Z}/n\mathbb{Z}

, such that the 101 functions

g(x), \quad g(x) + x, \quad g(x) + 2x, \quad \dots, \quad g(x) + 100x

are all bijections on

\mathbb{Z}/n\mathbb{Z}

Plain-text mathematical notation (without MathML)

Let Z/nZ denote the set of integers considered modulo n (hence Z/nZ has n elements). Find all positive integers n for which there exists a bijective function g:Z/nZ→Z/nZ, such that the 101 functions
g(x), g(x)+x, g(x)+2x, …, g(x)+100x
are all bijections on Z/nZ.

Original LaTeX notation

Let $\mathbb{Z}/n\mathbb{Z}$ denote the set of integers considered modulo $n$ (hence $\mathbb{Z}/n\mathbb{Z}$ has $n$ elements). Find all positive integers $n$ for which there exists a bijective function $g: \mathbb{Z}/n\mathbb{Z} \to \mathbb{Z}/n\mathbb{Z}$, such that the 101 functions
\[g(x), \quad g(x) + x, \quad g(x) + 2x, \quad \dots, \quad g(x) + 100x\]
are all bijections on $\mathbb{Z}/n\mathbb{Z}$.
