This representation was first used in the proof of Cayley's theorem [4] to show a one-to-one correspondence between free labeled trees on n nodes and strings of length n-2.
He takes a modern, geometric approach to group theory, which is particularly useful in the study of infinite groups, focusing on Cayley's theorems first, including his basic theorem, the symmetry groups of graphs, or bits and stabilizers, generating sets and Cayley graphs, fundamental domains and generating sets, and words and paths.
For example, before the proof of Cayley's theorem (2) is introduced, students are asked to suggest possible correspondences between words and trees.
