Dino Cube first mass-produced version had pictures of dinosaurs depicted on each piece, which led to the adoption of the puzzle's current name of "Dino Cube". It is not known what the puzzle had been called before this dinosaur version was introduced. The later versions, however, adopted the practice of using standard single-colour stickers, in common with most other twisty puzzles. The Dino Cube is a twisty puzzle in the shape of a cube. It consists of 12 movable pieces, all of which are located on the edges of the cube. The puzzle can be thought of as twisting around its corners:
Partial cube partial cube labeling. The isometric dimension of a partial cube is the minimum dimension of a hypercube onto which it may be isometrically embedded, and is equal to the number of equivalence classes of the Djoković–Winkler relation. For instance, the isometric dimension of an formula_9-vertex tree is its number of edges, formula_13. An embedding of a partial cube onto a hypercube of this dimension is unique, up to symmetries of the hypercube. Every hypercube and therefore every partial cube may be embedded isometrically into an integer lattice, and the lattice dimension of the partial cube is the minimum dimension of
