We have 5 blocks denoted A, B, C, D, and E. Let's stack them in two layers such that block A and B are on the top and blocks C, D, and E are on the bottom. Call this arrangement ABCDE: Let there be three groups consisting of blocks ACD, blocks ABD, and blocks BDE. Each move consists of choosing ...
