[Unofficial] my patterns 2x2x2 to 20x20x20 cube

Is the 20x20 actually manufactured?

You make me laugh sometimes :)

Nope. That's would be crazy though lol. It takes people hours and hours to solve that thing.

Well, just one "hours", but yes, it would be insane. On the other hand, they did make the Petaminx... that would probably take over an hour for the best computer solvers, although many of them haven't tried one. It would be similar, very few people would ever do it in one sitting...
