Solutions upper intermediate pdf

There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of outer-layer solutions upper intermediate pdf, called “face turns”.

The letters L, R, F, B, U, and D indicate a clockwise quarter turn of the left, right, front, back, up, and down face respectively. Half turns are indicated by appending a 2. The letters M, S and E are used to denote the turning of a middle layer. M represents turning the layer between the R and L faces 1 quarter turn top to bottom. S represents turning the layer between the F and B faces 1 quarter turn clockwise, as seen from the front. E represents turning the layer between the U and D faces 1 quarter turn clockwise left to right.

The letters X, Y and Z are used to signify cube rotations. X signifies the rotation of the cube forwards 90 degrees. Y signifies the rotation of the cube to the left 90 degrees. Z signifies the rotation of the cube clockwise 90 degrees.
