@Gerhard Paseman Do you think those cube states are random samples of all possible cube states, or somehow biased? |

@Francois Brunault Well, I'm allowing rotations of the face, so 4^3 = 64 states are possible once we fix one face, but you're absolutely right. What I'm trying to understand is, what is the probability that the solved cube is one of those states? Or are those states more or less a random sample of all possible cube states? |

@Brendan McKay Version (1) is what I had in mind. I don't want to condition on the cells being in the correct positions for a solved cube. |

@Francois Brunault I'm looking to make a statement of just how frequently you can solve the cube when you fix one or more faces. The answer, no doubt, will be "very infrequently". |

@Alexandre Eremenko Right, I'm having some trouble understanding how this problem works in the continuum limit, so I keep talking about Manhattan distances instead of Euclidean distances (where I'm not sure why it makes sense to talk about them on a lattice). Small $L$ means $L \leq 100$ or so. |
