1Letters (Speffz)

Edges

Corners

Cube white on top, green in front (as in the WCA scramble). Faces: U white A-D, L orange E-H, F green I-L, R red M-P, B blue Q-T, D yellow U-X; on each one clockwise from the top-left corner / top edge.

Letter from colours: sticker colour = face, the piece's other colours = which edge or corner of that face.

Buffers: edges UR (B, M), corners UBL (A, E, R) - these letters never go into the memo.

4Order

Tracing: the letter of the sticker in the buffer, then the letter of the sticker sitting in that position, and so on. Letter pairs = images (words).
Cycle break: the buffer's own piece comes back to the buffer while something is still unsolved - note the letter of any unsolved piece and trace from it until you get back to it.
Flipped edge / twisted corner in place = two of its letters.
Execution: each letter = setup, algorithm, undo. All the edges first.
Parity (odd number of edge letters): after the edges, once
R U R' F' R U2 R' U2 R' F R U R U2 R' U'
Then all the corners.

l = L with the middle layer, d = D with the middle layer. Undo = setup moves in reverse order, each in the opposite direction. Edge setups: only L, D, l, d; corners: only R, D, F.

Each letter: setup, algorithm, undo the setup. l = L together with the middle layer, d = D together with the middle layer. Odd number of edge letters = parity (Ra-perm) before the corners. StrefaKostek.pl
