Professor's Cube the Eastsheen 5×5×5 and the V-Cube 5 are designed with different mechanisms in an attempt to remedy the fragility of the original design. There are 98 pieces on the exterior of the cube: 8 corners, 36 edges, and 54 centers (48 movable, 6 fixed). Any permutation of the corners is possible, including odd permutations, giving 8! possible arrangements. Seven of the corners can be independently rotated, and the orientation of the eighth depends on the other seven, giving 3 (or 2,187) combinations. There are 54 centers. Six of these (the center square of each face) are fixed in position. The
Dino Cube the limit by 2. The edge pieces cannot be flipped or misorientated (See "Solving"), therefore this is also not taken into account. The total number of possible combinations on the six-colour Dino Cube is therefore equal to: This number is low compared to the number of combinations of the Rubik's Cube (which has over 4.3×10 combinations) but still larger than many other puzzles in the Rubik's Cube family, notably the Pocket Cube (over 3.6 million combinations) and the Pyraminx (just over 930 thousand combinations, excluding rotations of the trivial tips). The number of possible of configurations, 19 958 400, is
