y means to rotate the entire cube about the axis that connects U and D, rotating 90-degrees clockwise in the direction of a U move.
Subsequently, one may also ask, what does Y mean in Rubik's Cube notation?
y - rotate the entire cube on U. z - rotate the entire cube on F. Whole cube rotations can be marked with either lower or uppercase letters.
Also to know, what is Y in cubing?
y : rotating the cube on the Y axis. (U & D faces remain intact) z : rotating the cube on the Z axis. (F & B faces remain intact)
God's number is 20. The algorithm which gives an optimal solution in the sense that there is no shorter solution is called God's algorithm. There are cube positions (for example the superflip which flips all 12 edges), which are known to have a shortest maneuver length of 20 moves to be solved.
