Uses the newly defined Cayley graph (SimpleGraph.mulCayley) to state that connectivity of the Cayley graph is equivalent to the generating set generating the group. A foundational result in geometric group theory. Bumps mathlib to include the Cayley graph definition PR. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
