. Nearly all of the fastest speedcubers have based their methods on Fridrich's, usually referred to as CFOP, that is, (Cross, First 2 Layers, Orientation of the Last Layer, Permutation of the Last Layer). The method describes solving the cube in a layer-by-layer fashion. First a "cross" is made on the first layer, consisting of the center piece and four edges (Cross). Next, the first layer's corners and edges of the second layer are put into their correct positions simultaneously in pairs (F2L). The last layer is solved by first orienting the yellow pieces (OLL) and then permuting the last layer of the cube using a few sets of algorithms (PLL).
