p = R3 U2 B1 L3 F1 U3 B1 D1 F1 U1 D3 (12 q) Then p + (p * Sm) = SuperflipThis is Mike's process slightly patched, with the last two (commuting)

cube turns swapped in position.

i'm surprised this hasn't been pointed out previously. however, i would

write the above as

(R3 U2 B1 L3 F1 U3 B1 D1 F1 U1 D3 C_X)^2

where i use C_X for central reflection. this fits in with mark's

idea of "cyclic decomposition".

i've noticed that a number of minimal (or presumed to be minimal)

maneuvers for pretty patterns have some symmetry. here i'll use

commutator notation:

[ A , B ] refers to A B A' B'

also i'll use bandelow's notation for rotations of the whole cube:

C_U , C_RF , C_URF ,

denote rotation about a face-face axis, edge-edge axis, corner-corner

axis, respectively.

now some patterns:

anaconda: B1 R1 D3 R3 F1 B3 D1 F3 U1 D3 L1 F1 L3 U3 = [ B1 R1 D3 R3 F1 B3 D1 , C_UB ] python: D2 F3 U3 L1 F3 B1 D3 B1 U1 D3 R3 F1 U1 B2 = [ D2 F3 U3 L1 F3 B1 D3 , C_UF ] 6 x's (order 3): R2 L3 D1 F2 R3 D3 F1 B3 U1 D3 F1 L1 D2 F3 R1 L2 = [ R2 L3 D1 F2 R3 D3 F1 B3 , C_UB ] my favorite example is four twisted peaks: U3 D1 B1 R3 F1 R1 B3 L3 F3 B1 L1 F1 R3 B3 R1 F3 U3 D1 = [ U3 D1 B1 R3 F1 R1 B3 L3 F3 , C_R2 ]

i'd hoped to find maneuvers for "cube within a cube" and "cube within a

cube within a cube", but no such luck.
