Symmetry in Finite Geometry and Combinatorial Design

The provided sources explore the mathematical and artistic intersections of finite geometry, specifically focusing on the Cullinane diamond theorem and its square-based representations of PG(3,2). By utilizing 4×4 and 4×6 arrays, these works illustrate how combinatorial designs, such as Latin squares and Miracle Octad Generators, relate to highly symmetric structures like the Mathieu group M24 and the binary Golay code. The texts demonstrate that properties of symmetry, such as the affine group AGL(4,2), govern both abstract group theory and visual patterns found in puzzles, quilt designs, and sphere packings. This framework extends into coding theory and quantum mechanics, where geometric "bricks" and "lines" help simplify the analysis of complex lattices and error-correcting systems. Ultimately, the collection bridges rigorous algebraic abstraction with interactive visualization, showing that the logic of finite space underpins both mathematical truth and aesthetic form.
