4x4 PLL Parity Algorithms. When you are solving a 4x4, PLL parity can significantly slow down a solve. Luckily, there are some tricks you can use to minimize the damage without learning too mamny new algorithms. Some algorithms in this set are similar to PLL algorithms you already know, except there is a parity algorithm mixed in.Getting the Square-1 into a Cube Step I: Get the puzzle into 3 distinct layers Step II: Fill one layer with 6 large wedges Step III: Transform the puzzle into a cube Step IV: Orient Corners then Orient Edges Step V: Permute Corners then Orient Edges Step VI: Fix Parity and do Special Moves Notation (UR UB) (DF DB) (UF UB) (DR DB) Notation Top layer 30° (1/12 turn) CWEdge Parity on a 5x5 occurs when you pair the last edges and one edge doesn't match. This is because the two "wings" need to be swapped. Perform this algorithm with the flipped edge piece in the front top position. Rw U2 x Rw U2 Rw U2 Rw' U2 Lw U2 3Rw' U2 Rw U2 Rw' U2 Rw'.

We introduce a new family of rank metric codes: Low Rank Parity Check codes (LRPC), for which we propose an efficient probabilistic decoding algorithm.

4x4 parity occurs on the last layer of a 4x4, where you get a case that is not possible on a 3x3. This page show algorithms to solve it. PLL parity specifically occurs because two edge pieces are swapped diagonally with 2 other adjacent edge pieces. Generally you can't recognize it until you are at the last stages of your solve.algorithms with the top layer as the U face. Part 4: Last Layer Cross Your first objective is to orient the last layer edge pieces so they all have yellow facing up, forming a yellow cross on the last layer. The orientation of your last layer edges has three possible cases: F R U R' U' F' F U R U' R' F' Do both of the above algorithmsRound brackets are used to segment algorithms to assist memorisation and group move triggers.

Inspect your cube: If two corners are already lined up you are in luck. All you need to do is rotate the top layer to place the other two at the front, then a single iteration of the algorithm to switch them. If none of the above then you'll have to apply the algorithm twice. This is a large algorithm which can be difficult to remember.
