Cubology Lab — Rubik's Cube in (ρ, σ, v, w) notation

Drag a sticker to turn its face or slice · drag the background to rotate the view · scroll or pinch to zoom · keys R L U D F B and M E S twist (hold Shift for inverse)

Sequences read left to right. Inverses: R', R⁻¹ or R^-1; powers: R2, (RU)3, (RU)^-2; commutator [A,B] = ABA⁻¹B⁻¹. Slices: M (follows R), E (follows D), S (follows F) — these carry the centres with them, so the position vector is read relative to the rotated centre frame.
