The video at the bottom of the page is a work of art.

Now someone should build a robot to actually work that thing.

A few days ago, my younger daughter was trying to have fun and suggested that we watch an important video about solving a 1x1x1 Rubik’s Cube. I went along, and we spent some time moving up the numbers; that’s when we needed to search for the largest number of NxNxN possible, and we landed on this video and the article.

Isn't a 1x1x1 rubik's cube a dice ? Or i am missing something about the size notation ?

My daughter was making fun of me!

You still have to solve the minimum number of rotations to get the "1" at the top and the "3" in front

Isn't the minimum number of rotations always 0? IE you start with an already solved cube?

Maximum number of rotations is more interesting, although in the 1 cube that is just 2.

The minimum is not over all starting configurations, but over all move sequences for a fixed starting configuration.

Wow no kidding, I actually watched the whole thing.

The stop motion of the build was very satisfying. It’s also amazing how smoothly it moves, even being as heavy as it is.
