While it has 43 quintillion possible moves, it can be solved in incredibly few moves. Then it may be encoded into physical state of other body such as a book, hard drive or Rubik's cube, but the mind is still needed to transform the state into information. (Please correct any physics mistakes I've made) Let's start big, and make our way down to the smaller increments, shall we? First it measures the state and stores it in some digital memory. Its mathematical description is expressed by the Rubik's group, whose elements define how its layers rotate. Changing one bit of information in a Rubik's cube takes at least energy kT ln 2. There are several different sized Rubik's Cube games. Suppose I build a machine which will be given Rubik's cubes that have been scrambled to one of the $\sim 2^{65}$ possible positions of the cube, chosen uniformly at random. This will help you understand the mechanics of the Cube and more quickly solve it. What if the computer needs to solve a very large number of cubes and doesn't have enough memory to store them all? In order to apply group theory to solving Rubik's cubes, we first need to understand how Rubik's cubes work. Since in principle neither operation requires energy, there is no thermodynamic cost. Like the 5x5x5 , the V-Cube 7 has both fixed and movable center facets.   Terms.

Even if we assume that information entropy of the environment increases as a result of the process, this by itself is not sufficient to conclude that thermodynamic entropy does the same. With millions of cubes out there and countless would-be champions looking for tips to improve their times, this is the definitive manual for this unique sport. "giving it an infinite memory is very much the same thing as giving it an infinite source of energy" - that's a rather fascinating statement. I am not sure though. Yes, there is a long history of machines built to solve Rubik's cubes, but while they are very impressive in terms of speed, they are big and bulky and, crucially, not actually Rubik's cubes themselves. How do we know that it is impossible to solve the cube without recording the position in the machine's state? How is information different than the set of physical arrangements in physics? @CarlWitthoft As always, the amount of information assigned to an ensemble is observer-dependent. from $0.57.

David Joyner uses mathematical toys such as the Rubik's Cube to make abstract algebra and group theory fun. This updated second edition uses SAGE, an open-source computer algebra system, to illustrate many of the computations.

If information entropy was the same thing as thermodynamic entropy and the whole process could be reasonably described as reversible thermodynamic process, one could think that this is accompanied with system giving off heat to the environment since Clausius has shown that in such case $\Delta S_{thermodynamic} = \int dQ/T$. Sure, but the question is, supposing we are not going to record the information on a second cube (or anywhere else), can we then justify the conclusion that the machine must give off heat? I am not sure why you use expression "physically meaningful".

Solving the Molecube by Reduction. I guess this is more boring than the question intended :-( . What sort of argument does it take to say that a certain type of information is physically meaningful, such that destroying it necessitates paying an entropy cost somewhere else?
