For instance, $480$ is a Jordan–Pólya number because $480=2!\\cdot 2!\\cdot5!$. Every [[tree|062D9KXJB1]] has a number of symmetries that is a Jordan–Pólya number, and every Jordan–Pólya number arises in this way as the [[order|0B85S2V2DR]] of an [[automorphism group|0CWXCWP0Y0]] of a tree. These numbers are named after Camille Jordan and George Pólya, who both wrote about them in the context of symmetries of trees.\n",
