Dual Affine Robinson–Schensted

An interactive calculator for the map w ↦ (P̄, Q̄, λ, N₀) of Huang & Zhang (arXiv:2605.20383). Type the window of an extended affine permutation.

Affine growth diagram

Hover a shadow line to highlight it. Marks ● are tiles with w(j)=i; the bold box is the first stable window ΩN₀.
Tabloid row r is drawn in the colour of shadow-line colour r — the same colour as in the diagram.
