碰到个数据结构的题目，没什么想法，大家能帮忙看看嘛

题目是：
A site allows a user to customize their profile, in which they can set the shape of a logo to be between a circle, triangle, square, pentagon and hexagon, along with the logo being either red, green, blue, or any combination of them. In addition to this, it allows the user to have four rotational options for the logo (upright, turned left, turned right, or upside down). Create a data structure along with accompanying get/set functions that will store this information in the most space efficient way.

大家觉得这个用什么ds比较好？ 没碰到过这种题目， 没什么思绪。

The most space efficient way的话就把去重后每种情况编个号，get取相应的值就行了。去重就考虑哪个shape旋转了本质相同就行了。

放integer里，用bit存？
