Diabolical cube seven and nine pieces respectively. However, writes that the diabolical cube appears to be the oldest puzzle of this type, first appearing in an 1893 book "Puzzles Old and New" by Professor Hoffmann (Angelo Lewis). Because all of the pieces have only a single layer of cubes, their shape is unchanged by a mirror reflection, so a mirror reflection of a solution produces either the same solution or another valid solution. The puzzle has 13 different solutions, if mirrored pairs of solutions are not counted as being distinct from each other. Diabolical cube The diabolical cube is a three-dimensional dissection
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
