Internal pieces are excluded because the state count tracks stickers only.
Visually distinct states
Not computedVisually distinct states = distinct-piece states ÷ reachable indistinguishable arrangements.Reachable indistinguishable arrangements = 48,708,493,958,471,199,415,506,599,153,950,129,703,565,945,470,976 × reachable fraction.The reachable fraction accounts for restrictions such as permutation parity. Computing the correct fraction and the final visual state count is not yet implemented.

Checkerboard

(2L2 4L2 6L2) (2D2 4D2 6D2) (2B2 4B2 6B2)

Generalized alternating-layer checkerboard, verified against every sticker on each face. Even cubes have four checkered faces and two solid faces.

Outer-layer Superflip

U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2

Outer-layer adaptation of the published 3×3 Superflip: all edge rows flip in place, corners stay solved, center colors stay on their faces.

Outer-layer cube in a cube

F L F U' R U F2 L2 U' L' B D' B' L2 U

Outer-layer adaptation of the published 3×3 cube-in-a-cube pattern.

Six spots

U D' R L' F B' U D'

Outer-layer adaptation of the published 3×3 Six spots. The larger interior squares form the spots.
