Rubik Patterns

In the pattern sequences below F, T, K , B, R  and L are all clockwise turns of the Front, Top, bacK, Bottom, Right and Left faces. The lower case letters are anti clockwise turns of those same faces.

To make the two colours per face checkerboard pattern shown on the right do 180 degree turns of 3 x opposite faces (say 180 degree turns of Front, Back, Left, Right, Top and then Bottom) Repeat the pattern to correct the cube.

The sequence of turns F2 K2  T b  L2 R2  T b
will make for the 4 hole cube shown left. Top and bottom will be left untouched. Reverse the process to return the cube to its former state.

The sequence of turns T b   K f   R l   T b
makes for a 6 hole cube. It, as always leaves the centre colours as they were moving the top, right and back face colours clockwise around the top right back corner and the bottom front and left colours anticlockwise round the bottom left front corner.

Reverse the process to return the cube to its former state but remember to have the same top and front centre face colours. Alternatively just seek and suitably position the three face colours that need rotating clockwise and repeat the same sequence.

If you perform the sequence that produced the two colour checkerboard pattern and then follow that with the sequence that produced the 6 hole pattern you will get a checkerboard pattern as shown left with three colours per face.

You can reverse the two sequences but alternatively as for the 6 hole pattern you can repeat both patterns if you first identify the three corner block colours that need clockwise rotation.

The sequence R L K F performed 3 times will make for a zig zag pattern around the cube sides as shown left. Repeat the sequence to restore the cube to its completed state.

The sequence of moves
F2 R2 T2  f  K  B2 L2  F K  will make for a pattern of T’s on each of the 6 cube faces as shown in the illustration right. The reverse of the sequence k f  L2 B2 k F T2 R2 F2  will reverse the process and restore the cube.

The sequence of moves
F T F R L2 K b R B2 L b K R2 L F T F
will make for a pattern of stripes around the sides of the cubes as shown. The reverse sequence f t f l R2 k B l B2 r B k L2 r f t f
will undo the stripes

The sequence of moves
F k T F T F T L K L2 k T f  L T l  K will make for the arrow head pattern illustrated right.  The reverse of the sequence
k L t l F t K L2 k l t f  t f t K f  will restore the cube. Alternatively position the cube so that the 3 L shaped colours at the top right front corner need a clockwise turn and then do the same move sequence that made the arrow pattern again.

Sequence F L F t R T F2 L2 t l K b k L2 T  makes for an 8 cube block with a 27 cube block. Note that the sequence rotates the L shape colours around the top right corner cube clockwise so to correct the cube simply position the other diagonally opposite corner of the cube at the top right hand and repeat the sequence.

The cube in a cube in a cube pattern shown right is the result of sequence F B f B2 l k T L B R T l f T L T2
It is one block within an 8 block cube within a 27 block cube.

To reset the cube reverse the sequence .
