Hyperbolic Tessellation — Poincaré Disk

Schläfli symbol {p,q}

p (polygon sides) — 4

q (polygons at vertex) — 5

Recursion depth — 4

Color mode

{p,q} hyperbolic when (p−2)(q−2) > 4. In Poincaré disk, hyperbolic lines are circular arcs perpendicular to the boundary circle. Angles are preserved (conformal), but areas grow exponentially with distance. Infinite tessellation fits inside the finite disk.
