Cyrillicns developed new Cayley graph generation capabilities for the cayleypy/cayleypy repository, focusing on the symmetric group S_n with 3-cycles. They implemented two Python APIs, three_cycles and three_cycles_0ij, enabling researchers to efficiently construct and analyze Cayley graphs using permutation group theory. Their work included comprehensive unit tests to ensure correctness and robust handling of edge cases, with particular attention to graph diameter analysis through the “Diameter three cycles” commit. By emphasizing both feature delivery and test coverage, Cyrillicns improved the reliability and research readiness of the codebase, demonstrating depth in graph theory, software development, and testing practices.
