After 4Cubes this is the second collaboration between Oskar van Deventer and Tony Fisher. The puzzle even follows its predecessors concept.
The idea of this version was Oskar�s, inspired by Tony�s idea for 4Cubes. The design was made by Oskar. The sponsoring was made by Tony. There was one failed prototype before this collaboration was successfully finished.

All moves on both 4x4x4s are possible except the four slices which would cut through the disk. And additional move allows to exchange the halves of both parts. This makes up for a total number of four different types of turns.

Tony chose to use 12 colours to sticker the puzzle. One cube has traditional colouring and the other has the less common colours like purple etc.

The puzzle has 797131554370611148828844844835351625123271449907149002462677298180523880585245476153126549304824792350720000000000000000000000 = 797*10^123 permutations if all pieces are considered distinguishable.
Compared with the number available if the puzzle can be disassembled and reassembled there are these restrictions:
-The orientation of the last corner is determined by the other fifteen.
-The permutation of the corners and the X-Pieces have the same parity.
Stickered as shown here the puzzle has 43654105742904425827740614512237933278787291285864790235879110544742920079713328630333440000000000000000000000 = 43.7*10^108 permutations.
The first number is significantly higher than the doubled 4x4x4:
Size(Super CubesOnADisk)/Size(Super 4x4x4)^2 = 226126646546633820000/81719

Size (cube to cube; outer edges): 108 mm
Edge length (cube): 48 mm
Diameter (disk): 98 mm
Weight: 144 grams
