Floppy Cube turning - i.e. an edge piece may only twist if there is at least one corner piece adjacent to it. The mass-produced version does not feature this mechanism, which allows edge pieces to twist "on their own" - causing the puzzle to be considerably easier. The four edge pieces now have 4 orientations each on the Super Floppy Cube (compared to the Floppy Cube's 2); therefore, the edges can now be orientated in 4 different ways. However, the edges still cannot be permutated. There are now 12 different locations that the four corner pieces could be located in (up from
Folded cube graph nearly the same vertex degree but only half the diameter. Efficient distributed algorithms (relative to those for a "hypercube") are known for broadcasting information in a folded cube. Folded cube graph In graph theory, a folded cube graph is an undirected graph formed from a hypercube graph by adding to it a perfect matching that connects "opposite" pairs of hypercube vertices. The folded cube graph of order "k" (containing 2 vertices) may be formed by adding edges between opposite pairs of vertices in a hypercube graph of order "k" − 1. (In a hypercube with 2 vertices, a pair of
