1Orientation, order, rules

Orientation: white centre on top, green in front. Letters as in 3x3: U L F R B D, clockwise. Order: x-centres, t-centres, corners, wings, midges.
X-centres and t-centres (buffer B): the colour from the buffer goes to the first wrong position in alphabetical order on its own face; white: D, A, C; cycle break: first wrong position. Setup, U2, undo. A ↔ C after an odd number of earlier letters. Odd: U2.
Corners (buffer A): as in 3x3, modified Y. No parity - odd number of letters: for the wings and midges A ↔ D, E ↔ Q (look at the other position).
Wings (buffer K): setup, 2R2, undo; C ↔ W. Odd: wing parity. Midges (buffer U = DF): as in 3x3; setup to A, 3R2, undo; C ↔ W, I ↔ S; always an even number of letters.

Corners: no algorithm - swap A ↔ D, E ↔ Q for the wings and midges.

Undo = the setup backwards, every move in the opposite direction.

Each letter: setup, fixed move (U2 / Y-perm / 2R2 / 3R2), undo. After an odd number of earlier letters of a given kind, the letters of a pair swap roles: A↔C (x-centres, t-centres), C↔W (wings), C↔W and I↔S (midges). Odd number of corner letters: for the wings and midges UL and UB are swapped (A↔D, E↔Q). StrefaKostek.pl
