1Orientation, letters, order

Orientation: white-green-red corner at the front right on top, white up (C, J, M always solved). Letters as in 3x3: U L F R B D, clockwise; centres from the top left, wings - the half that comes first clockwise.
Centres (buffer B): the colour from the buffer goes to the first position in alphabetical order on its own face with a wrong colour; white: D, then A, C. Cycle break: white in the buffer and the whole top white - first wrong position. Each letter: setup, U2, undo. A ↔ C after an odd number of earlier letters. Odd number of letters: U2.
Wings (buffer K): like edges in 3x3, without flips. Setup, 2R2, undo. C ↔ W after an odd number of earlier letters. Odd number of letters: wing parity.
Corners (buffer A): as in 3x3, modified Y. Odd number of letters: corner parity after the corners.

Each letter: setup, U2 (centres) / 2R2 (wings) / modified Y (corners), undo. After an odd number of earlier letters of a given kind, target C instead of A (centres), W instead of C (wings) - and vice versa. Odd number of letters of a given kind = parity after that part. StrefaKostek.pl
