Learn to Solve Rubik's Cube 3x3x3
Provided of course you know the 99 turns. But why?
We know that this 99turn has a magicnumber which we do not know beforehand. But if we repeat this 99turn repeatedly, we will reach this magicnumber (and a restored Rubik's Cube). In Group Theory (a university Math course), this magicnumber is called the order for this 99turn. This 99turn and all its repeats together form a cyclic group of order=magicnumber. Interestingly, the 198turn (consisting of two 99turns) has a different order which is a divisor of the 99turn order. This theory is useful because it reassures us that the repeatuntildone trick is possible. But honestly, if you know the 99turn, you could just do the reversed turns in reversed order.
You can enter a move in DBLFUR notation:
 Each turn is [DBLFUR]['i"2]  Example 1: FUB2UF' (5 turns)  Example 2: D,L,R",D',L' (5 turns)  [DBLFUR]::Down,Back,Left,Front,Up,Right face.  By itself, each means clockwise 90° turn.  ' or  or i means anticlockwise 90° turn.  " or 2 means 180° turn. or BFR (GANPuzzle) notation:

Solving the Rubik's Cube is very difficult for most people. So slow down and learn. The reward is a lifetime of immense pride and joy that you can share with people around you.

Here is a learning Tip. Scramble cube and save to file.
• From reset state ( ) the move when repeated 6 times returns to the reset state. Magicnumber (actually known as order) of the move is 6.
• If we denote donothing move by I,
RightTopX move by a, RightTopX twice as a^{2},
3times as a^{3}, etc., then
{a,a^{2},a^{3},
a^{4},a^{5},I
} forms a cylic group with 6 elements,
{a^{2},a^{4},a^{6}=I
} a subgroup of 3 elements (of order 3),
{a^{3},a^{6}=I}
a subgroup of order 2; a^{3} interestingly swaps 2 pairs of corners, so
to swap back, just repeat a^{3}. Try
.
• Fact: Any move sequence, no matter how simple or complex generates a cyclic group.
• Fact: A cube when scrambled with 99 turns can always be restored by repeating the same 99turn until done because we know there is a magicnumber .
