四重

And if you think about it, all these different societies have different geometric design themes they use. So Native Americans use a combination of circular symmetry and fourfold symmetry. You can see on the pottery and the baskets ... Here's an aerial photograph of one of the Anasazi ruins; you can see it's circular at the largest scale, but it's rectangular at the smaller scale, right?

事实上，不同的社会有不同的几何建筑规划方案，在北美，人们喜欢圆形对称、四重对称，你可以在陶罐和篮子上看出来……这是Anasazi遗迹的航拍图，图上看出大局上呈现圆形，而局部则呈现方形。
