A deep-dive into how geometry shapes permutations. We plot points on refined grids, impose rules per cell, and explore monotone grid classes, cell graphs, and row-column connections. We’ll connect these visuals to word encodings and trace monoids, learn why these classes are partially well-ordered, and see how growth can be described by forbidden patterns and polynomial-rate descriptions—delivered with intuition, examples, and clear intuition.
