A colleague told me about a news post I should read, detailing that a new upper boundary for solving the Rubik’s Cube has been found – now 25 moves, instead of 26. While this in itself is interesting, the way it’s described in the news post is even more interesting:

He’s shown that there are no configurations that can be solved in 26 moves, thereby lowering the limit to 25.

What the poster probably meant to write was that there’s no configuration that requires 26 moves, and not that solving the Rubik’s Cube is never possible in 26 moves 😉

None the less, this is great news – with luck, we may soon be able to play with our Rubik’s Cubes in a way we know is truly optimal!
