4/29/2023 0 Comments Square 1 edge permute algorithmIf exactly one of the two layers is a valid PLL case and the other one isn't, your square-1 has parity. 5 It is absolutely necessary to know which PLL cases are valid on a 3x3 (knowing full PLL is highly recommended, experience in 4x4 or 6圆 solving is very helpful). This is the earliest point in a Vandenbergh solve where you can recognize parity in a reasonable amount of time. Method 2: After edge orientation, before corner permutation (Intuitive or algorithmic) (-2, 2) / (2, -2) // swap three corners with 3 corners to change parity The easiest way to get three adjacent corners on both top and bottom is to go to the scallop-scallop shape: / (-3, -3) / (2, 1) / // go to scallop-scallop The easiest way to do this is two swap three corners with three corners. Parity means you need to perform and odd swap of pieces. You can always use it later in the solve and then re-solve what it destroyed. However, if you absolutely do not want to learn a parity alg at all, this a possible method for you. I'm not suggesting this as a serious speedsolving method simply because recognition is terrible. Method 1: After cubeshape, before orienting corners - INTUITIVE METHOD 4 The main disadvantage is that they're relatively inefficient and will add a whole additional step to your solving method. The main advantage of these methods is that you only have to learn one single algorithm. Solve parity between two successive steps Generally speaking, the earlier you solve parity, the harder it will be to recognize but the shorter your algorithm(s) will be. Theoretically parity can be recognized and solved at any point of the solve. Permute edges - bring all of the edges to their correct position 3 Permute corners - bring all of the corners to their correct position Orient edges - bring all of the edges to their correct layer Orient corners - bring all of the corners to their correct layer 1, 2įor clarity I will first outline the basic steps of the Vandenbergh method - though some of the parity methods below are also applicable to other solving methods.Ĭubeshape - return both U-layer and D-layer to a square shape. A square-1 with an odd number of swaps "has parity". That means having an odd number of total swaps to perform will be generally harder than having an even number of swaps to perform. In most cases though, doing two swaps at a time is way easier and shorter. Unlike on a 3x3 it is possible to swap any two pieces of the same type in a single swap. Square-1 is a puzzle with 8 edges and 8 corners.
