Pieces

Type	Count	Stickers	Positions	Orientation (physical)	Orientation (visual)
4	4	3	4	3	3
4	6	2	6	2	2
4	4	1	4	3	1

One row per orbit. Orientation counts are per position; multiple values mean positions differ.

Distinct-piece states

≈ 3,732,48044,789,760 arrangements of the stickers the moves reach (Schreier–Sims)÷ 12 turns of the whole puzzle= 3,732,480Tracks individual sticker identities, even on identical-looking pieces; whole-puzzle rotations are identified. Invisible rotations of a piece and internal pieces are not counted.

Visually distinct states

Not computedVisually distinct states = distinct-piece states ÷ reachable indistinguishable arrangements.Reachable indistinguishable arrangements = 1 × reachable fraction.No visually interchangeable sticker-bearing pieces were found.The reachable fraction accounts for restrictions such as permutation parity. Computing the correct fraction and the final visual state count is not yet implemented.
