Mathematics is the study of patterns. The most fundamental and elementary type of pattern is a symmetry. There are finite `groups' of symmetries, such as the group consisting of the 48 distinct symmetries of a cube, and there are also infinite groups of symmetries such as the group of symmetries of the tiling of the Euclidean plane by squares. While finite groups of symmetries can be understood quite well, some infinite groups are so complex that they are provably impossible to understand. Nevertheless, many important problems in geometry and topology can be reduced to understanding the infinite group of symmetries of some infinite geometric object.

数学是对模式的研究。最基本和基本类型的模式是对称性。有有限的对称性组，例如由多个立方体的48个不同的对称性组成的组，并且还有一个无限的对称性组，例如通过正方形的欧几里得平面平铺的对称性组。尽管有限的对称组可以很好地理解，但一些无限的群体是如此复杂，以至于不可能理解它们。然而，可以简化几何和拓扑中的许多重要问题，以理解某些无限几何对象的无限对称性群体。
