HATO Puzzle
Simple as it looks, HATO is a 4 dimensional cube.
HATO consists of a 2x2x2 cube and 6 smaller embedded 2x2x2 cubes therein. Embed is a term in mathematics, we think it is also a suitable description of this structure.
Compared with software simulated 4d cubes(2^4 cube), the total number of positions of HATO is significantly larger.
Behind the name. Our planned launch of this product was stopped by a Typhoon named HATO and subsequent blackout for a whole week. See [url]https://en.wikipedia.org/wiki/List_of_retired_Pacific_typhoon_names[/url] for the explanation of the name HATO itself. The day when HATO hit Zhuhai & Zhongshan, our colleagues fought against it and kept our lost to minimum. In order to mark this event, we took the name of HATO for this project. Patterns on the sphere was added after this event and was inspired by Typhoon sign and Auspicious Clouds.
It comes assembled, stickered and packaged.
