MEMO 2017 Problem 7

    Determine all integers n≥2n \geq 2 such that there exists a permutation x0,x1,…,xn−1x_0, x_1, \ldots, x_{n - 1} of the numbers 0,1,…,n−10, 1, \ldots, n - 1 with the property that the nn numbers x0,x0+x1,…,x0+x1+…+xn−1x_0, \hspace{0.3cm} x_0 + x_1, \hspace{0.3cm} \ldots, \hspace{0.3cm} x_0 + x_1 + \ldots + x_{n - 1} are pairwise distinct modulo nn .
