Problem Statement

A competition involving n2n\ge 2 players was held over kk days. In each day, the players received scores of 1,2,3,,n1,2,3,\ldots , n points with no players receiving the same score. At the end of the kk days, it was found that each player had exactly 2626 points in total. Determine all pairs (n,k)(n,k) for which this is possible.
