Sm = Central Reflection

i.e. for operators

     F1 = B3, F2 = B2, F3 = B1
     L1 = R3, L2 = R2, L3 = R1
     U1 = D3, U2 = D2, U3 = D1

p = R3 U2 B1 L3 F1 U3 B1 D1 F1 U1 D3    (12 q)

Then  p + (p * Sm) = Superflip

This is Mike's process slightly patched, with the last two (commuting)
cube turns swapped in position.
