Problem 4 (due Monday, March 30)

Let p>2 be an odd prime number. Integers a1,a2,,ap+1 in the interval [0,p] have the following property: for every permutation π of the set {1,2,,p+1} the number p+1k=1kaπ(k) is not divisible by p. Prove that a1=a2==ap+1.

Ashton Keith, a freshman majoring in math, is the only person who solved the problem. His solution is based on a different idea than our solution. Both solutions are discussed in the following link Solution
