Patterns & Best known solutions Last Update: Sept. 15, 1997 ------------------------------- Use the following sequences generate the described pattern from a solved state, and it's inverse to get back from the pattern to a solved state. In general patterns with T for Top are my own discoveries, while ones containing U for Up are the work of others. The contributions of Mike Reid, Dan Hoey, Dik Winter and Hans Kloosterman have been invaluable. The number of moves of a process is (N), which may be suffixed by s to indicate slice moves. After () L indicates that this process is a local maximum After () S indicates that this process is shift invariant Some alternative sequences result in a pattern rotated with respect to the original sequence. s1 2x2x2 antipode (F1 R1) ^2 + F1 D2 F1 D3 F1 D2 R2 (11) (note this uses < f, r, d > group only) p1 6 X of order 3 R2 L3 D1 F2 R3 D3 F1 B3 U1 D3 F1 L1 D2 F3 R1 L2 (16) (rotates edges 120

yellow, B = red, L = green 6 Diagonal (twist orbit) Using the 4x4x4 cube we can produce a single exchange of centres and an exchange of edge pairs, and we can invert a single edge pair. Thus we can construct all the impossible 3x3x3 patterns except those involving a twist of a single corner! Impossible Patterns (possible by peeling off stickers!) ------------------- 6 Cross order 2 (Note this is not the same as p14 above as this pattern tries for opposite colour crosses on opposite sides) This pattern may also be created by unscrewing the centres and exchanging them.

Centre of the Cube Group ------------------------ The centre of the cube group is the process which commutes with every other process, the only nontrivial example is the 12-flip Properties ---------- Local Maxima, Global Maxima, Shift Invariance Comments on Patterns -------------------- Note that the cube consists of 8 corners with 3 colour tabs and 12 edges with 2 colour tabs, e.g. 8 * 3 = 12 * 2 = 24 The cube can be oriented in space 24 different ways The dodecahedron can be oriented in space 60 different ways 4 DOT is an example of a permutation in the squares group which can be solved faster using q and h moves There are positions which have only opposite colours on all six sides which are NOT in the squares group (See p36) Colourings ---------- There are 7,983,360 ways to 12 colour the dodecahedron (12! / 60) = 7,983,360 There are 30 ways to 6 colour the cube ( 6! / 24) = 30 On a 3 coloured cube, with opposite faces having the same colour, there are 6 orientations in space. The rotation group of the dodecahedron is A_5 and is simple.
