This is a classic problem of distributing distinguishable objects (artifacts) into indistinguishable bins. The number of ways to distribute \( n \) distinguishable objects into \( k \) indistinguishable bins is given by the sum of Stirling numbers of the second kind, \( S(n, k) \), summed for \( r = 1 \) to \( \min(n, k) \): - Abu Waleed Tea
