A short introduction to rows, columns, modular wrapping and phase, with a worked example.
Learn the constructionFinite rules. Open questions.
Modular arithmetic, symmetry, phase, and structure.
Explore arithmetic grids. Follow the rule, change a parameter, and see what happens.

A grid becomes easier to understand when its size, indexing and arithmetic rule are explicit. Start small, then compare.

Separate the construction you can specify from a pattern you observe and a statement you can prove.
Results and open questionsRead a plane, compare an orientation or separate the phases in space. Each view keeps its construction in reach.
It does not finish the argument. Definitions, finite checks and mathematical proofs answer different questions.
The tools state their arithmetic and indexing. An attractive image is an invitation to investigate, not evidence for a physical or computational application.
From small hand-drawn grids to interactive instruments: follow the development of Naglich Squares, with mathematical questions and exploratory interpretations kept distinct.
