Problem Statement
We are given identical cubes, each of size . We arrange all of these cubes to produce one or more congruent rectangular solids, and let be the number of ways to do this. For example, if , then one arrangement is twelve cubes, another is one solid, another is three solids, another is three solids, etc. We do not consider, say, and to be different; these solids are congruent. You may wish to verify, for example, that .Find, with proof, the integer such that .
